POLICE are questioning a man after a road-rage incident in which witnesses claim a P-plate driver deliberately attempted to run down four cyclists today.
Police had been looking for a small red sedan that drove into a group of four cyclists on Marmion Avenue, Iluka, in Perth's northern suburbs, about 7.40am (WDT) today.
Police spokeswoman Libby O'Brien said a person had given himself up at Warwick police station and was assisting police with their inquiries.
One cyclist has suffered a suspected broken finger and grazing after he and three other riders were targeted in an apparent road rage attack in Iluka this morning.
Witnesses have told police the driver of a small red sedan drove into one cyclist, knocking him over the car bonnet, before swerving toward three other riders at the intersection of Marmion Ave and Burns Beach Rd in Iluka at about 7.40am.
Gary Bell, one of the cyclists in the group, told ABC Radio a red Mitsubishi Lancer pulled up near him and his fellow riders at a red light and sounded its horn at the cyclists.
Mr Bell said it was lucky none of the group were dead, and believes they were deliberately targeted.
"I really think it is not a normal reaction for anyone - he deliberately tried to kill us.''
Mr Bell said he was in no doubt the P-plater, who he suspected must have been on drugs, was trying to kill them.
Police spokesman Ros Weatherall said the act appeared to have been deliberate.
"One cyclist was knocked off his bike and has a suspected broken finger,'' she said.
"There are some reports that the driver has reversed over one of the bikes.''
Ms Weatherall said police had been given the registration number of the car involved in the incident and a man was now being questioned.
