Resident carried terrified children away from home
Ely resident Rob says he and his partner tried to leave their home with their newborn baby and two other children at about 01:00.
But the way was blocked by police in one direction and a burned car in the other.
Officers, he said, told them to leave on foot.
He said: “We couldn’t get out, we were stuck. I carried my three kids to my dad’s [house] a few streets up."
He said they were terrified.
"I ended up stood outside in my front garden, you had to protect your house," Rob said.

IOPC issues statement
The Independent Office for Police Conduct (IOPC) has issued a statement after South Wales Police referred itself to the police watchdog.
It says: “We have been contacted this afternoon by South Wales Police to make a referral regarding the circumstances leading up to the fatal collision in Ely yesterday.
"We will be sending investigators to a police post-incident procedure to begin gathering information and to assess whether the IOPC will carry out an independent investigation.”
A very difficult 24 hours
Tomos Morgan
Reporting from Cardiff
There's a lot of people out on the streets already tonight questioning what happened last night.
Ely has had a reputation over the years. The Ely riots took place almost 32 years ago.
It took a number of years for the community here to get rid of that reputation, but it also has a reputation as a close-knit working-class community and I've seen that as the day has gone on.
Flowers have been laid in the street where those fatalities took place. Earlier today, friends and families have come together to grieve together.
But people have also spoken about a distrust in the police and the way things have transpired today.
This morning South Wales Police hadn't referred themselves to the IOPC, but has since said it has.
So there will be distrust and there will be anxious voices here again tonight because they will want answers.
There'll be sympathy for the families and sympathy for the residents here after what has been a very difficult 24 hours.
New footage raises questions about police account
Tomos Morgan
Reporting from Cardiff
There are a lot of questions tonight, especially in this area.
When we arrived here this morning, there was dismay really from the residents on the street because so much of their property had been damaged by the riots that happened last night.
And the rumours were rife, rumours that the police had, in some way, been involved in the death of the two boys which happened hours before the riots began here in Cardiff.
New footage has now come to light and seems to question the version of events given by the police in the run up to the two teenagers' death yesterday.
Call for probe into police handling of events
Calls have been made by politicians for an impartial investigation into police handling of events in Cardiff.
Following the emergence of CCTV, which appears to show a police van following two people on an electric bike before the crash, the Welsh Liberal Democrats have urged South Wales Police to publish their timeline of events.
Cardiff Liberal Democrat leader, Rodney Berman, says there are "serious questions" over the police version of events.
“This incident needs to face an immediate, impartial investigation," he said.
Plaid Cymru MS for South Wales Central Heledd Fychan echoed Mr Berman's sentiments, saying an independent investigation was "essential".
South Wales Police has referred itself to the Independent Office for Police Conduct (IOPC).
Witness describes disorder in Ely after crash
The BBC has spoken to a man who lives near the crash and scene of the riot in Ely and described what he saw last night.
Felix, who asked we do not use his full name, said he didn't hear the crash but saw traffic "piling up on the bottom of my road" at some point between 18:30 and 19:00, followed by "shouting and some screaming" a few minutes later.
He says after going to see what was happening, he saw "numerous police officers and dozens of people gathered round", but at that point he says there was "only slight disorder" - rather than arson or vandalism.
But Felix also says around an hour or two later he heard "significantly more shouting, and then a few screams".
Quote Message: Later on into the night, I began to hear loud bangs and a strong smell of smoke outside, along with even more shouting. A police helicopter started circling above, along with a very large and noisy drone overhead."

Ashes, debris and wreckage at Cardiff riot scene

The BBC's Tomos Morgan reports from Ely in Cardiff where two teenagers are understood to have died in a crash before a riot broke out.
'You wonder if it's going to happen again'
A resident named Dean says he heard "cars on fire" and "explosions on Stanway Road” at between 19:00 and 20:00.
The 34-year-old was at home with his partner and two young children.
He said: “Then about 10:30 I heard the helicopters above and sirens, police telling people to get away from the cars and the explosions.
“There was smoke billowing from the street, it was absolutely atrocious.
“It makes you wonder if it’s going to happen again."
CCTV footage captured about half a mile from crash
The CCTV footage appearing to show a police van following the scooter or electric bike was recorded on Frank Road - about half a mile from the crash.
The video's time stamp shows it was recorded at 17:59 on Monday, shortly before the fatal crash on Snowden Road in Ely.
For anyone who'd like a sense of the distance between them, we've made a satellite map of the area to help:
