Colac police Sergeant Wayne Dennehy said  another two such crimes had been reported to police on Tuesday morning after thieves smashed windows to gain entry to vehicles. 

"There were another two last night and we've had a spate of them recently," he said.

"Windows were smashed after the offenders identified valuables or potential valuables were visible.

“In addition to locking their cars, owners need to make sure their valuables are out of sight or even better still not left in their vehicles at all," he said.
