It's been a tough week for trusting homeowners in Penetanguishene.

There have beeen five house robberies this week -- all at homes that had been left unlocked.

In each case, the thieves made off with small electronics items, booze and cash during the overnight hours.

OPP in Penetang are asking people to keep an eye on their neighbours' homes.

They're also reminding you not to post on social media sites about your upcoming vacations.
