A youth accused of murdering the black teenager Anthony Walker has told a court he tried to help him.
Anthony Walker was attacked with an ice axe
Anthony, 18, was killed with an ice axe near the entrance to McGoldrick Park in Huyton, Merseyside, in July.
Michael Barton, 17, of Boundary Road, Huyton, is on trial for his murder, which he denies, at Preston Crown Court, sitting in Liverpool.
His cousin, Paul Taylor, 20, of Elizabeth Road, Huyton, has already said it was he who swung the axe.
He had denied murder but changed his plea to guilty in court last week.
Michael Barton, who is the brother of Manchester City footballer Joey Barton, was also charged with murder as the prosecution claims he supplied the weapon and was part of the attack.
Mr Barton told the court on Wednesday that he tried to help Anthony when he realised what had happened.
Asked what he saw that night in the park, he said: "Anthony Walker. He was lying there. He had something out of his head. I tried to help him. I tried to remove the weapon gently.
"I felt sick and in shock. When I couldn't move it I ran away back to the car."
Mr Barton said he and Taylor had "bumped into" Anthony, who was walking through McGoldrick Park with his cousin Marcus Binns and girlfriend Louise Thompson.
But the prosecution claims the pair hurled racist abuse at Anthony on the night that he died.
Anthony Walker was attacked near the entrance to McGoldrick Park
Mr Barton told the court Taylor was driving a car aggressively and parked it by McGoldrick Park.
The pair then jumped over the wall, where they saw Anthony, Marcus and Louise.
Mr Barton said: "One of the lads and the girl ran off so I chased the lad. Paul stayed there. I chased the lad up Grahams Road, then I heard a glass bottle smash so I went back to the park to see if my cousin was all right."
The story Mr Barton told in court was different to the original one he told police, which the court had heard on Tuesday.
He originally claimed he had been standing outside the Huyton Park pub when Marcus had approached him in an aggressive way.
Mr Barton said he had run away, then gone with Taylor to have a fight.
He claimed he had picked up the ice axe after seeing it randomly lying at the side of the pub.
However, when he was asked by defence barrister David Steer QC when he first saw the axe, he replied: "In Anthony Walker's head."
When asked whether he had a problem with black people, he said he did not and had met Anthony Walker more than once on the bus and had no problem with him.
The trial continues.
