Hill was arrested on Saturday on suspicion of causing actual bodily harm (ABH), a serious offence which carries a maximum sentence of five years in prison.

The 43-year-old was released on bail but will face further questioning and possible charges following the outcome of the ongoing police investigation.

China player Zheng Tao was knocked unconscious and suffered a broken jaw during the fracas, which resulted in the February 7 match being abandoned.

The incident is still being investigated by English football's governing body, the Football Association, as well as local police.

In a statement on Tuesday, the police said they were "continuing to investigate a number of assaults following a disturbance amongst players at a match between QPR FC and the Chinese Olympic team."

"All parties from both QPR and the Chinese team are assisting police."

Seven members of China's squad were sent home following the clashes, which involved more than 30 players and members of the coaching staff on both sides.

A statement from QPR read: "Following the incident at the training ground on February 7, and the subsequent police investigation of the matter, Queens Park Rangers Football Club have suspended assistant manager Richard Hill from his duties until further notice."

The club said it would not comment further on the issue pending the outcome of the FA and police inquiries.

The Chinese under-23 squad is in England as guests of Premiership champions Chelsea.

The Chinese FA has vowed to come down hard on players found to have been at fault in the incident, which has been widely condemned by the Chinese media as an embarrassment for the country in the countdown to next year's Beijing Olympics.

The brawl erupted when striker Gao Lin, one of the seven players to be sent home, lashed out following a tough tackle from a QPR player. Gao apologised for his inability to control himself but insisted he had been a victim of provocation.

China's coach Ratomir Dujkovic subsequently revealed that the players had all been warned to keep themselves in check in the wake of violent incidents in two earlier matches on their tour.
