Kamloops RCMP responded to a robbery in progress this morning at the Cornerstone Market on 12th Street.
A male entered the store and threatened the clerk with a syringe while demanding money. The suspect made off with an undisclosed amount of cash.
The clerk was not harmed during the incident, said Kamloops RCMP spokesperson Cpl. Cheryl Bush.
A suspect was taken into custody by police shortly after the incident, but there may have been a second male involved.
Police later located a blue Toyota Tacoma pickup that departed from the robbery, but have not said anything more about a second suspect.
The investigation is ongoing, and anyone with information is urged to contact Kamloops RCMP or call CrimeStoppers to remain anonymous.
