Saskatoon police believe one group of people is responsible for five robberies Sunday night.

At approximately 9:30 p.m., a pizza delivery person was robbed at Avenue Q and 19th Street by a lone male suspect.

Just after 2 a.m. Monday morning, a man and woman broke into a home in the 500 block of Avenue X South. The two were armed with a handgun, and made off with cash and video games.

A third incident happened at 3:52 a.m., when a cab driver was robbed at gunpoint by a man and woman in the 3700 block of Diefenbaker Drive. The gun was fired during the incident and the cab driver suffered minor injuries.

Only twenty minutes later, a man entered a convenience store in the 1400 block of 22nd Street and pointed a gun at two customers inside. Police are still looking for the victims in this incident.

Finally, at 4:23 a.m. a business in the 800 block of 22nd Street was robbed by a man believed to be armed with a handgun.

Employees were able to record a vehicle description and plate number and police have made an arrest as a result. A 22-year-old male suspect is in custody, and police are searching for several other suspects.

Anyone who witnessed these crimes is asked to contact the Saskatoon Police Service or Crime Stoppers.
