All four people killed in a crash on Friday night, following a police car chase, have been named.
Adnan Ashraf Jarral, 35, and his one-year-old baby boy Usman died when the VW Touran people carrier they were travelling in was hit by a Golf that had been pursued by police.
Two other people, Vlasta Dunova, 41, and her husband Miroslav Duna,50, also died in the smash in the Darnall area of Sheffield, shortly before 9pm.
Their 22-year-old daughter, Nikola Dunova, was injured and remains in hospital in a serious but stable condition. Her daughter, aged three, Livia Matova, who was also in the car, remains in a critical condition.
Mr Jarral's uncle, Shafqat Mirza, told Sky News correspondent Tom Parmenter, who is in Darnall, that his nephew was a "unique character, very humble, very polite – he was full of life and devoted to his sons. He would do anything for them".
"He was always taking them out on trips, shopping, fun fairs…he was very very close to his kids."
Mr Mirza confirmed that his nephew's wife, who is originally Slovakian, was in the vehicle but survived and is being treated in hospital for a broken leg, back injuries and minor facial injuries.
He revealed they had been planning a trip to Mecca on 27 November.
Mr Jarral had been driving the people carrier home after a trip to London when they were hit by the VW Golf at 8:50pm on Friday evening.
A South Yorkshire police vehicle had been pursuing the VW Golf at the time of the crash and the incident has now been referred to the Independent Office for Police Conduct who are carrying out their own investigation.
Tufail Hussain, 80, was one of the first people to get to the wreckage of the crash after hearing a loud bang outside his home.
Mr Hussain said: "It was just terrible. It's the worst thing I have ever seen.
"The whole of Darnall is in shock. We are all traumatised and it will take a long time for us to get over this."
He said an off-duty paramedic who lives on the street performed heroics at the scene.
Medics from a private medical support firm, based a few hundred yards from where the collision happened, also came to help.
Mr Hussain said: "The whole community is shocked but they have pulled together. Everyone came together to help."
Detective Chief Inspector Jude Ashmore, leading the investigation, said on Sunday: "We are continuing to support both families and we have specially trained officers with them. My thoughts are with them and I'd ask that people continue to respect their privacy as they try to digest what's happened.
"Our investigation into the collision continues and the road closure around Main Road was lifted last night and the two vehicles removed. I'd like to thank everyone for their continued support, cooperation and patience.
"Officers have remained in the area today and will be there into the evening and tomorrow. I'd urge anyone who saw what happened to speak to them, you may have important information and officers can also offer and direct to any necessary support if you need it.
"We remain keen to hear from anyone who saw what happened, or who may have footage of the collision. If you have information that could assist with the investigation, please call 101 quoting incident number 741 of 9 November 2018. You can also speak to Crimestoppers anonymously on 0800 555111."
