A 29-year-old St. Catharines man has been arrested and charged in connection with two convenience store robberies in Port Colborne and Welland over the weekend.

The robberies

According to Niagara Regional Police, officers from the service's 6 District responded around 10:31 p.m. on Saturday, October 10, to a reported convenience store robbery in the area of Main Street East and Dolphin Street in Port Colborne.

Police said a male suspect entered the store, brandished a knife and demanded cash. He fled westbound on a bicycle with an undisclosed amount of money and other items. No injuries were reported.

The second robbery took place around 7:20 a.m. on Sunday, October 11, when 3 District officers were called to a convenience store in the area of Southworth Street North and Lewis Street in Welland.
