About 4am on Tuesday, three men allegedly broke into a home on Osprey Street in Harrison, stealing two handbags containing cash and electronic devices.

About 4.30am, a second home on Alice Crist Street in Franklin was allegedly targeted, with car keys and a watch stolen.

Police allege a third break-in occurred about 12.30am on Thursday, when three men stole a blue 2021 Mazda 3 hatchback from a home on Nimbera Street in Harrison.
