A GROUP of teenagers has been charged with allegedly stealing more than $1 million worth of items in Western Australia.

Police say the nine teenagers, aged between 15 to 17 years old, also caused more than $250,000 worth of damage during their burglary spree in October.

The teens were linked to a series of alleged burglaries on jewellery and retail stores in Bunbury, Busselton, Mandurah, Rockingham and Maddington, and police say they used stolen cars each time.

The teens were interrupted during an alleged jewellery store burglary in Mandurah on October 6, but evaded officers and damaged two police cars as they sped off.

Investigations led to police raiding several houses in Bunbury and Carey Park, where they say they found some of the stolen property, vehicles, cash and drug-related items.

The group has been charged with 171 offences and will face Bunbury Children's Court on March 17.
