A suspect was shot by an L.A. County Sheriff’s deputy Tuesday afternoon at the Expo Line terminus in Downtown Santa Monica, officials said.

The suspect was placed in an ambulance, but his condition was not immediately known. Sheriff’s spokesman Ramon Montenegro did not confirm whether or not the suspect was armed, although witnesses reported that he was brandishing a knife.

No deputies were injured following the incident, which happened at about 12:55 p.m., Montenegro said.

Road closures were in effect in the area around the transit station, which is located at Colorado Avenue and 4th Street.

Expo Line service was also disrupted, as trains were turning around at the 17th Street/Santa Monica College station. Bus shuttles were in service between the 17th Street stop and the terminus, according to transit officials.

Additional information was not immediately available.

The station opened in May. In June, the station was briefly evacuated as authorities cleared a suspicious package.

The sheriff’s department handles security for the L.A. County Metropolitan Transportation Authority. Santa Monica police were assisting.
