Toronto police are investigating at least three break-ins and robberies in the west end overnight.

Officers say around 11 p.m. Saturday, a man walked into a Mac’s Convenience Store on Martin Grove Road and demanded cash from an employee at gunpoint.

Then just after 2 a.m. on Sunday, a family awoke to find a man in their home near Islington Avenue and Bloor Street West.

It’s not yet clear if he took anything before he fled.

Soon after, there was a break-in at Humber Valley Village Junior Middle School on Hartfield Road near Islington Avenue and Dundas Street West.

The thief allegedly made off with an iPhone and a laptop.

There are no reports of any injuries, and so far police have not linked any of the robberies.

In late July, Toronto police issued a warning about residential break-ins in Etobicoke.

It’s believed the same suspect broke into several homes near Bloor Street West and Mill Road through unlocked windows and doors.
