A man wanted on warrants for breaching parole has allegedly been caught with drugs and a burglary kit after throwing a bike at Sydney police and trying to run away.


The 24-year-old tried to leg it after he and a another man were stopped by police patrolling at Central Railway Station early on Saturday afternoon, they say.


He allegedly threw a mountain bike at police, hitting one on the knee before bolting.


While being chased he was seen throwing a small bag over a fence, police said.


"The bag was ... recovered and allegedly contained an amount of white powder believed to be crystal methylamphetamine (ice) as well as housebreaking implements," a spokesman said.


He was later charged with several offences including possessing housebreaking implements and assaulting police.


He was refused bail and is due before Parramatta Bail Court on Sunday.
