Waterloo regional police are investigating two convenience store robberies they say happened less than an hour apart in Cambridge.

Officers were called to the first incident around 7:20 p.m. Friday in the area of Cedar Street and Berkley Road.

Officials say a man came into the store, demanded money while showing a knife, and fled with an unknown amount of cash.

Around 8:10 p.m., officers were called to another incident in the area of Cambridge Street and Bond Street.

It was reported again that a man entered the store and demanded money while showing a knife, but this time he was chased out of the store by an employee before police were called.

The Cedar Street robbery suspect is described as a white man between 40 and 60, and was last seen wearing a brown and green jacket, work boots, gloves and a blue mask. 

The Cambridge Street robbery suspect is described as a white man in his 30s, around 5'6, and with a heavy build. He was wearing black pants, a black baseball hat, and a multi-coloured bandana covering his face. 

The investigations are ongoing. Anyone with information is asked to contact Waterloo Regional Police Service.
