Upper St. Clair police are investigating an armed robbery at St. Clair Mini Mart on Route 19.
Township Manager Matthew Serakowski has confirmed that the employees were held at gunpoint and $600 was stolen on Monday night. He was unable to provide any additional information.
One of multiple officers confirmed to Patch that no one was hurt.
Just before 9 p.m., an officer was seen interviewing three employees inside the store. They appeared to be shaken up. A sign on the door said the store was closed. Vehicles were still outside using the gas pumps.
Patch will continue to monitor the situation.
