TV appeal in hunt for 'brutal' attacker

Leon Adams remains in a coma four months later

South Wales Police hope a television reconstruction will help them track down the attacker who left a man in a coma following a brutal assault in Cardiff.

Leon Adams, 25, from the Swansea Valley, was found unconscious at Grangetown railway station in the city in the early hours of St Valentine's Day.

Somebody that can do that much damage on a whim can do that much damage to anybody - friends or family

He had been working at a pub in Cardiff city centre on the night of the Wales-Argentina football match.

His last known movements were recreated by the Crimewatch team for transmission on BBC One on Wednesday night.

Detectives are hoping that the programme will prompt witnesses to come forward.

Cardiff city centre had been busy on the evening of 13 February.

Around sixty thousand football fans had packed the Millennium Stadium to see Wales draw 1-1 with Argentina in a friendly international.

Mr Adams was still in the city two hours after work

Mr Adams had been working at the Cottage pub in St Mary Street that night, leaving the premises about 1145 GMT.

But closed circuit television footage showed him near the central bus station just before 0200 GMT.

A number of witnesses say they saw what police believe may have been an argument between Mr Adams and two men.

Three hours later, just after 0500 GMT, he was found unconscious at Grangetown railway station, approximately a mile south west of the city centre.

Doctors say he had been beaten senseless, and four months later he remains critically ill in a coma at Morriston Hosptal, Swansea.

Despite a poster campaign, police are no closer to finding out why the attack took place, although Mr Adams's wages had been stolen.

Angie Murphy has been keeping a vigil

His mother, Angie Murphy, has been hoping for signs of recovery every time she visits her son in hospital.

"He doesn't know we're there - he can't move, his body is contorting," she said.

"Every day is a bonus - another day that he's alive."

She said she was anxious to see his assailants brought to justice.

"Somebody that can do that much damage on a whim can do that much damage to anybody - friends or family," she said.

Anyone with information is urged to call South Wales Police on 029 20 222 111 and ask for the Fairwater incident room
