A CTrain was forced to stop in the middle of a tunnel in downtown Calgary following an assault Tuesday night.

At about 11 p.m., Calgary police were called to 36 Avenue and Burnsland Road S.E.

Officials told CTV News they were called to the CTrain for reports of a stabbing after it left the Erlton-Stampede station.

The train car was in a tunnel at the time of the incident, and officers had to run down the tunnel to respond.

"Everyone started jumping out of the car, and we saw cops with huge rifles," said one witness.

"It was really scary."
