Several key routes around Sheffield city centre are still gridlocked as police divert traffic away from the incident.

Vehicles heading to the city from the east are seeing the longest delays and closures, with the closed Park Square roundabout a major route into Sheffield.

"We've tried to keep our spirits up because people are upset and concerned about what's gone on," he said.

"It's people's homes and possessions and there's a lot of anxiety, but we've just tried to be there for one another and ride it through as best we can. It's a bizarre situation."

Sam said staff at the sports centre have been providing hot and cold drinks, with air mattresses delivered to the venue at around 04:00 GMT.

"They aren't the comfiest, but you make do," he said.

Jack, from the nearby Street Kitchen Café, has told BBC Radio Sheffield some parents have been coming in with their children because their nursery is closed.

"I saw police at the bottom of our road and they had taped off the tram tracks," he said.

Not an awful lot has changed here at the Gateway apartments in Sheffield through the course of the morning.

We currently have about 10 police vehicles here and a few ambulances as well.

In the past few minutes, a welfare van has arrived to keep emergency crews hydrated with cups of tea and coffee.

It will have been a long night for some of them.

We’ve seen some armed police up inside the building and an ambulance crew bringing out a stretcher.

Residents have been evacuated from their homes in part of Sheffield city centre after armed police were called to reports of a man with suspected weapons inside a property.

South Yorkshire Police say they were called to the Gateway apartment building on Broad Street at about 19:00 GMT on Monday.

Some residents took refuge at the Ponds Forge sports centre, with university students staying at the nearby Pinnacles accommodation building told to stay inside their flats.

Police and other emergency services remain at the scene with the road closed.

There has been major and ongoing travel disruption in Sheffield city centre and beyond as a result of the incident.

There's major disruption to travel in and around Sheffield as a large-scale police operation continues in the city centre.

Armed police have been called to the Gateway apartment building on Broad Street after reports of a man with weapons inside a property.

Police say that as a result Sheffield Parkway, between Park Square roundabout and Derek Dooley Way, will remain shut for the time being.

Meanwhile, Sheffield City Council has closed the left-hand lanes on Shoreham Street to prevent people travelling towards Park Square roundabout.

There also appears to be major disruption to trams in the city, with no service on Sheffield Supertram between Sheffield Station/Hallam University and City Hall.

However, trains in the area seem largely unaffected.

Police say people should continue to avoid the area and plan alternative routes.

From where we’re standing on Broad Street, you can see a large number of ambulances outside the Gateway apartments.

Some ambulance crews have just gone towards the building wearing protective vests and helmets.

Police officers still stand guard at a large cordon as some students leave the nearby university accommodation building, which is The Pinnacles on Cricket Inn Road.

This is a huge response to an incident which has been ongoing for more than 12 hours.

Last night, I was here as armed officers closed streets and led people away from their homes.

It’s calm at street level now as officers continue their work inside the apartment block

This was the scene outside the Gateway apartment building on Broad Street in Sheffield earlier this morning.

Officers were called to the building at about 19:00 GMT on Monday, South Yorkshire Police said.

Residents were evacuated from their homes after armed police were called to reports of a man with suspected weapons inside a property.

People remain unable to get back into their homes again as the incident continues.

Luke, a travel agent in Sheffield, has told the BBC that he has been stuck in traffic in the city for some time due to the ongoing incident.

"It's a bit long," he says.

"I heard on the radio this morning, so when I came down on the Todwick roundabout I saw the queuing on the A57.

"I decided to go through Todwick, through Kiveton and Wales and it was just traffic everywhere.

"It was pretty much backed up. It took me an hour and a half to get to the Moor.

"It was just knowing the roads I suppose and being a Sheffield lad I know which ways to go."

Sean, 25, is among the local residents evacuated to the nearby Ponds Forge sports centre.

He tells the BBC: "It's been quite stressful, they've not really told anyone what's going on.

"None of us have eaten. There's been good spirit among us and security guards here have looked after us.

"But we're asking police questions and they're not telling us anything. So where do we go from here?

"We're freezing, cold and tired."

I've been down near the cordoned off area since earlier this morning.

People who have been evacuated have spoken of their "stress" about leaving their belongings behind.

Residents say they need more information about what is happening and what they need to do next.

"We, alongside other emergency services, remain on scene at Broad Street in Sheffield.

"Just after 19:00 we responded to concerns for a man inside a property, alleged to have weapons and pose a risk to himself.

"Those within the building where the property is have been evacuated and those within the neighbouring buildings have been asked to stay indoors while officers conduct their work.

"The Sheffield Parkway, between Park Square roundabout and Derek Dooley Way remains shut. Please plan, and find an alternative route this morning."
