We're closing our live coverage now, thank you for joining us.

It was a day of tributes and vigils in Nottingham, as the victims from yesterday's attacks were formally identified and friends and relatives began to speak about those who lost their lives.

A vigil at the University of Nottingham - where Barnaby Webber and Grace O'Malley-Kumar were students - drew thousands, while tributes were also left at the scene where school caretaker Ian Coates was killed.

You can read more about all three of them in this piece.

Meanwhile, the police investigation into the incident continues. A 31-year-old man is still being questioned on suspicion of murder.

This article examines everything we have learned so far about the attacks - from what happened to what we know about the suspect.

Today's page was edited by Owen Amos, Emma Owen, Sam Hancock, Dulcie Lee and myself, with reporting by our teams in London and Nottingham. You can continue to follow updates on this story here.

Toby Geddes, a friend of Barnaby Webber, has described the student as "a confident guy" and "great fun".

The fellow University of Nottingham student played cricket with Barnaby and also knew Grace O'Malley-Kumar from sports social events.

Toby said there was "a big link" between the cricket and hockey teams, of which Grace was a member, at the university and players from both groups would often socialise together.

"I just miss my mate, to be honest," he told the BBC, adding that it felt "surreal" to learn of Barnaby and Grace's deaths.

"[Barnaby] was passionate about his cricket and got stuck into all the social events and from what I've heard and other people have told me, he was a sports-mad kind of guy," Toby added.

"The best way we can deal with this is to speak to people about it and pull through together."

Speaking after the vigil held at the University of Nottingham this afternoon, the university's vice-chancellor said everyone was in a state of shock.

Prof Shearer West described it as a "very moving ceremony" and said it shows something positive that "students rally round in times of trouble".

Speaking to PA news agency, West said: "It's so very sad that their lives were cut off in the way they were."

Extra well-being and mental health support has been provided for students, she said, adding: "There obviously is a lot of anxiety because of this."

West expressed her "deepest condolences" to the family members who came to the vigil and those who "showed amazing bravery in speaking".

Nottingham is continuing to come to terms with yesterday morning's attacks in which two 19-year-old students and a 65-year-old man were killed. Here's an overview of what's happened today:

• Tributes have been paid to the three people killed in yesterday's attacks in Nottingham - students Barnaby Webber and Grace O'Malley-Kumar, and school caretaker Ian Coates
• At a vigil at the University of Nottingham this evening, Barnaby and Grace's families were joined by thousands mourning the loss of "two much-loved students"
• The students' fathers addressed the crowd and both spoke of their children's love for the university and how touched they were at the outpouring of support
• Earlier, Ian Coates' sons remembered their father as "everyone's friend", adding that "you genuinely couldn't find a nicer guy". One of the caretaker's sons also revealed his father was only months away from retirement
• It comes as police continue to question a 31-year-old man on suspicion of murder
• Meanwhile, the BBC has seen CCTV footage that shows a man said to be the suspect trying to climb into an open window at a homeless hostel either just before or during yesterday's incident

Tributes from sports clubs Grace O'Malley-Kumar and Barnaby Webber were members of have been pouring in throughout the day, and there's now another, this time from the University of Nottingham men's cricket team.

The team say they will mark their final game of the season with a two-minute silence before the match.

Ollie Chaplin, who plays on the team, says he knew Barnaby and Grace.

"No words can be used to describe them, they were incredible people," he says.

"Barney, I think we can agree for those who knew him was one of the nicest guys you'll ever meet."

Speaking about Grace, Chaplin adds: "She was one of my best friends. I can't describe how much I'm going to miss her."

We've been focusing on the vigil held at the University of Nottingham for students Grace O'Malley-Kumar and Barnaby Webber. But people have also been paying tribute to Ian Coates, the other person killed in Tuesday's attack.

A little earlier, family members of the 65-year-old school caretaker placed flowers and football shirts at a site in Magdala Road, near to where he was found.

His grandson left a bouquet of flowers with an accompanying note, which reads: "Missed every minute and every hour. We miss you dearly."

Ian's son, Lee, left a vintage England shirt with a message in marker pen reading: "Dad, love you always and forever."

Another son of Ian's, James, draped a Nottingham Forest shirt on the pavement with a message written on it, which said: "Dad, taken too soon, rest in peace, you will be missed. Love you, J x"

I've just spoken to two first-year medical students who used to attend dissection classes with Grace O'Malley-Kumar.

Finlay tells me: "It is shocking to think that someone I spent time with there is now gone. It's really sad she is not here any more."

Emma, another of Grace's classmates, adds: "I think overall Nottingham is a safe city, I am just going to be a lot more careful."

Thousands of students and members of the public gathered at the University of Nottingham to mourn the loss of Grace O'Malley-Kumar and Barnaby Webber a short time ago.

Many students wore sports kit, including from the women's hockey team, marking the passions of both victims.

Various speakers addressed the crowds, including the university's vice-chancellor Shearer West, who said people had come together to remember "two much-loved students".

A minute of silence was held, before students and staff were invited to lay flowers.

Grace and Barnaby's father then addressed the crowds.

"I've lost my baby boy," said Barnaby's father David Webber. "He loved it here. He couldn't wait to come back. It drove me mad," he joked.

Grace's father Sanjoy Kumar thanked everyone for coming and said: "The love that we have out here, I just wish we had it everywhere. So, look after each other is the big thing."

As we've been reporting, the fathers of Barnaby Webber and Grace O'Malley-Kumar have just addressed a vigil for their children who were killed on Tuesday.

Both parents said their children loved life at the University of Nottingham - you can watch their tribute below:

The main part of the vigil has finished now, but let's bring you a few more details of what Grace's father said a few moments ago.

He told the crowd that his daughter loved coming up to Nottingham, adding: "In fact we couldn't get her down.

"I said to her last week 'come down', and she said well, after she's had a few more sessions," he joked.

"I used to call them her crisis meetings," he said, which was met with laughter from the crowd.

He said it meant so much that people had taken the time to come.

"You all touched her life and hence ours - you'll never be forgotten."

The vigil has a very sombre atmosphere, with raw grief rippling through from the families to the wider student community. Audible tears. Lots of hugging.

At least a thousand students have gathered, maybe more. The sports teams are here in their kits supporting each other through this.

Flowers have been laid by families and friends for Barnaby and Grace.

We're now hearing from Grace O'Malley-Kumar's father, who thanked everyone who came to the vigil.

Grace's father says it is a "lovely sign of the university and the bond you have".

He says Grace loved being at the university and was full of stories of her time there.

Taking pauses to gather himself, he tells the crowd: "So look after each other is the big thing, look after your friends and look after people around you."

We're now hearing a few words from Barnaby Webber's father.

“I’m lost for words, I’ve lost my baby boy," David Webber tells the vigil. "I know Barney would be super touched by everyone here."

David reminisces about how much Barnaby loved it at the University of Nottingham.

"His heart will be with you guys for ever," David says as he hands the microphone to Grace's father.

Rev Grant Walton has invited people to lay single-stem flowers. Members of the hockey team join first, followed by more students and staff who lay the flowers in near total silence.

The families of Barnaby and Grace lay their flowers and link hands together as they walk off and embrace students.

After the minute of silence, two students are invited to come forward to light candles.

This is followed by representatives from across the university stepping forward to lay flowers.

The vigil is drawing to a close with a minute of silence.

We're now hearing from the University of Nottingham's vice-chancellor who says it is hard to find the words to express the shock and grief.

Shearer West says: "What should have been a time of celebration and relaxation following the exam period has become a time to mourn tragic loss in the most unimaginable of circumstances."

The university is supporting Grace and Barnaby's family, she says, adding that support was available to any students or colleagues affected by this tragedy.

Addressing the vigil, West said that the university and communities across Nottingham have come together in "grief and remembrance of two much-loved students".

The University of Nottingham's student union community officer Daisy Forster is next to speak at the vigil as she says the deaths of first-year students Grace and Barnaby are a "monumental loss".

"The shock waves echo thorough our student community," she says.

She pays her condolences to the victims' sports teams, families and friends.

"We will always be here when you need us," she tells the families of Grace and Barnaby as she points out thousands of students are behind them.

"It is okay to cry, it is okay not to," she concludes.

We've just had this photo from the scene at the vigil, showing the sheer number of people who have turned out to remember Grace O'Malley-Kumar and Barnaby Webber.

Rev Grant Walton, from the university chaplaincy, has opened the vigil by thanking students, staff, community and the families of Grace and Barnaby for attending.

"The main point of being here is to talk with one another, not to be talked at," he says as he hands over to the University of Nottingham's vice-chancellor Shearer West.
