THE streets surrounding a house party where a Burnley teenager was knocked down and killed were packed with people following a series of skirmishes, a court has been told.

Partygoers in surburban Christchurch, New Zealand, spilled out into the road to watch the fighting - shortly before former boxer Lipine Sila ploughed through the crowds, his murder trial heard.

Former Ightenhill schoolgirl Jane Young and Hannah Rossiter, both 16, received fatal injuries in the incident and 28 fellow revellers were hurt, some seriously.

Factory worker Sila, 22, has pleaded not guilty to two counts of murder, and eight charges of intentionally wounding or causing grievous bodily harm.

The High Court jury hearing the case spent the second morning of the trial being taken by bus to the scene of the incident.

Jurors viewed the stretch of suburban road, around which the allegations revolve, with markers showing where those injured had ended up.

Later two witnesses described the street fighting that took place during an out-of-control party on May 5 last year.

One said he believed Lipine Sila confronted his brother wielding a bottle minutes before the car careered through the crowd.

Ian Howard Hitchcock told the jury that he saw someone in the roadway who he later recognised as Lipine Sila's brother, Ben.

Ben Sila was challenging everyone to fight him and throwing bottles which hit a passing bus, a police car, and broke the window of a parked car, he said.

Mr Hitchcock said he saw his friend Joseph Craig Muir move towards Ben Sila at that stage. Sila backed off but Mr Hitchcock then saw two men come at him and his brother who were following Mr Muir and a fight began.

Mr Muir, 20, said he chased Ben Sila away and then returned, where he recognised one of the men who had fought with his friends and shoulder-charged him and punched him beside a parked car.

The man, said to be Lipine Sila, was knocked down, and then knocked down again onto the car's bonnet, the court heard.

That fight ended when Mr Muir - a fitness instructor student and rugby league player - was struck from behind and began fighting someone else on the footpath, the court heard.

"I then heard a car revving," said Mr Muir. "I heard a noise like . . . duff-duff-duff and I saw some bodies lying there."

Cross-examined by defence counsel Pip Hall, Mr Muir said he had not seen any group of skinheads at the gathering, had not heard white power slogans, and did not hear or use the words, "nigger" or "coconut".

He acknowledged that he broke his knuckle in the fighting that night, but did not know when.

He denied that he had tried to get into the car that Lipine Sila had driven, to get people out of it. He said he did not see people trying to smash the car with bottles, and did not see the back window get smashed.

He said he did not push the head of any Samoan forcefully into a brick fence pillar during the fighting.
