Justin Bieber has been charged with dangerous driving and assault, according to Canadian police.
The 20-year-old pop star was arrested after a collision between a minivan and a quad bike apparently led to a physical altercation in southwestern Ontario.
Ontario Provincial Police said the incident happened Friday afternoon (August 29) near Bieber's hometown of Stratford and that he was released on a promise to appear in court September 29.
They said the driver of the quad bike and an occupant of the minivan "engaged in a physical altercation."
Bieber went to a police station and was arrested, then released on a promise to appear in court September 29, a spokesman for Perth County OPP said.
OPP Constable Kees Wijnands said there were no injuries as a result of the collision, but could not say whether there were any injuries from the altercation.
Bieber was photographed recently in southwestern Ontario riding on a quad bike with actress and singer Selena Gomez.
Earlier this month, Bieber pleaded guilty to misdemeanor charges of careless driving and resisting arrest seven months after his arrest in Miami Beach following what police initially called an illegal street drag race.
Bieber is also charged in Toronto with assaulting a limousine driver in late December. Police allege Bieber hit a limousine driver several times in the back of the head after he and five others were picked up by a limo in the early hours of December 30.
His lawyers have said he is not guilty in that case.
Also in Miami, Bieber faces a lawsuit by a photographer who alleges he was roughed up while shooting pictures of the singer outside a recording studio.
Bieber rocketed to fame at age 15. He was nominated for two Grammy Awards for his 2010 full-length album debut My World 2.0, but sales of his latest records have fallen off.
