Warrnambool Police have reminded the public to be vigilant, following four thefts from motor vehicles late last week.

Between Thursday night and Friday morning (Nov 12-13) two vehicles were targeted in Skiddaw Crescent, while thefts were also reported in Thompson and Verdon Street.

Acting Senior Sergeant Tom Morris from Warrnambool Police, said unfortunately the vehicles targeted appeared to be unlocked.

"It's just a reminder for all people out there, to just make sure that they lock their vehicles when they do leave them" he said.

"We aren't victim blaming, we're just ensuring that people do a bit of crime prevention themselves to stop these offenders in their tracks"

One of the vehicles was parked behind closed gates, while three of the four incidents saw wallets stolen.

"In one instance they've stolen a wallet and some cards, which were used at a local service station, police are following up with CCTV from that location"

"We get calls of people trying car door handles and moving on, we eventually catch up with those people and we do arrest and charge them, but the theme is that they target unlocked vehicles"

"We're obviously trying to determine if these are all linked, anyone with information can contact the Warrnambool Police Station".
