Hamilton police say they believe a series of robberies that have occurred at local businesses during the past two days may be related.

The robberies, which took place on March 6 and just past midnight on March 7, featured a lone male approaching the cashiers in four separate businesses and demanding money from the tills.

In three of the robberies, the man was armed with a knife, but no one was injured.

Hamilton Police media relations officer Debbie McGreal-Dinning said it is too early in the investigation to confirm a connection, but there is a possibility that they may be linked.

In the first robbery, which took place around King Street East and Ashley Street on March 6 at approximately 3:45 a.m., the suspect was described as a 40-year-old white male with a heavy build, black hair and goatee, wearing a green and black jacket and black pants. In this instance, the suspect was not armed with a knife.

The second robbery took place at a variety store near King Street East and Wentworth Street South on March 6 at about 7:10 p.m. Witnesses described the suspect as a 30-year-old Hispanic male with tanned skin, 6 feet tall with a heavy build, wearing a grey hood and a black mask over the bottom of his face.

In the third robbery, which occurred in the area of Main Street East and Wellington Street on March 6 at 9:40 p.m., the suspect is described as a white male in his 40s, 5 feet 4 inches with a heavy build, thin dark brownish-grey hair, wearing a black jacket and dark pants.

The fourth robbery happened on March 7 at about 12:30 a.m. around the area of King Street West and New Street. The suspect is said to be a white male around 5 foot 8 inches tall with a medium build, short brown hair, light facial hair, wearing a green winter jacket, blue jeans, brown shoes, and a shirt wrapped around his face.

Anyone with information on any of these incidents is asked to call Hamilton Police at 905-546-4925.
