Mr Bampton, a construction worker, was on his way

home following a night out with work colleagues in Bristol city

centre when he was attacked.

He was walking with a friend down Marsh Street, behind the

former Bristol & West tower between Baldwin Street and

Broad Quay, when a passing car stopped in the early hours of

yesterday morning, at about 2.30am.

The driver got out and punched the man once, knocking him to

the floor close to the BT building. He is thought to have

smashed his head on the building or pavement as he fell.

Police believe the attack was random and unprovoked and have

yet to establish a motive.

An ambulance rushed him to the BRI, but unfortunately

doctors were unable to save him.

His parents were understood to have been at his bedside when

he died at about midday yesterday. They remained too upset to

speak.

The 28-year-old lives in Southampton but had been in Bristol

for work. It is not known how long he had been in the city.

Marsh Street remained closed yesterday afternoon as forensic

experts gathered evidence at the scene.

Detectives have been scouring CCTV footage from city centre

cameras and last night urged the driver to give himself up.

Police have also pleaded for a private hire taxi driver who

they believe was in the area at the time to come forward.

There are at least two cameras which look down the street,

one from Broad Quay and the other from Baldwin Street.

Nearby buildings are also thought to have cameras which

would have been operating at the time.

Detective Superintendent Andy Williams is leading the murder

hunt.

He said: "We believe there was one blow which resulted in

him falling to the floor.

"I am urging the person responsible for this offence to come

forward.

"This may have been a spur of the moment action and it is

very possible that they did not realise the seriousness of the

assault at the time.

"Therefore I am appealing to their conscience to contact us

immediately."

He added: "We are following a number of lines of enquiry,

particularly CCTV footage, and it would be better for all

concerned for the person responsible to speak to us sooner

rather than later."

He also appealed for anyone who knew about the attack to

come forward.

He added: "Did someone you know come home and say they had

been in a fight or looked like they had?"

Police are also keen to speak to a taxi driver who was seen

nearby at the time of the incident.

He said: "Again, it is possible that this taxi driver did

not realise how serious this assault was and we urge them to

speak to us as they could be a vital witness."

Witnesses should call Bristol police on 0845 456 7000 or

ring Crimestoppers on 0800 555111.
