London police have seized thousands of dollars worth of drugs after two major busts on Thursday.

Members of the guns and drugs section, which includes officers with London police and the RCMP, executed search warrants at two homes – one on King Street and the other on Oak Crossing Gate.

Investigators say they seized over $400,000 worth of cocaine, crystal meth and heroin, three loaded firearms, ammunition, a silencer and cash.

Crystal Carrier, 24, Ryan MacDonald, 27, Scott Wells, 28, and Ashley White, 26, are charged with several controlled drugs and substances offences.
