Christopher Hanley, 57, died after being found unresponsive on Olympic Street, in Beswick, near Manchester city centre, just before 11am on Saturday.

Flowers have been left near the scene of what a local person called a "horrible" incident.

Police have said their initial inquiries suggest Mr Hanley was killed when he was hit by a black Land Rover as he tried to stop his car being stolen.

He was pronounced dead at the scene, despite the efforts of members of the public and emergency services.

A 35-year-old man arrested on suspicion of murder and a 43-year-old man arrested on suspicion of assisting an offender are being questioned.

Mr Hanley's family said in a statement issued through police: "As a family we are heartbroken and shocked at the sudden loss of Chris, a loved and devoted family man who adored his grandchildren, tragically and unfairly, taken way too soon."

A resident said: "It was horrible. I'm still shocked. These houses are OK but we are surrounded by estates. We've had quite a bit of trouble around here, more so than where I used to live in Longsight."

A local man who did not want to be named, said he was woken up by a car revving and soon afterwards, "the street was full of blue lights.

"One of the people who responded first, she was an off-duty nurse, she was the first person there and may have called the police.

"It has been a bit of a shock, but no one knows who he was, so we are all in the dark. It's not like you know one of your neighbours and he has been killed. We don't know who he was or if he was local."

He described that part of Beswick, around half a mile east of the city centre, as "a quiet residential area".

Flowers have been left at the roadside on Holly Street, at the bottom of Olympic Street, which had a damaged street sign, but locals said this was not as a result of Saturday's incident.

Detective Chief Inspector Rachel Smith from Greater Manchester Police's Major Incident Team said: "At the centre of this investigation is a grieving family, who we will do all we can to get answers for.

"Our investigation is moving at pace, and I have a team of detectives who continue to work relentlessly to capture a picture of what happened in the events leading up to this incident."
