A dog is currently receiving veterinary treatment after a BART police officer shot and wounded the animal at the Civic Center BART station Friday afternoon.

The incident occurred at 1:10 P.M. at the station's stairwell when the dog "aggressively lunged" at the officer, according to an email statement from BART spokesman Jim Allison. The animal was described as an "unleashed pit bull type dog."

Market Street was closed in the Civic Center Plaza area and about two dozen officers were on the scene as of 1:45 p.m.

"BART had an incident that is currently under investigation," said an officer at the scene who would not confirm any further details.

There were no signs of the dog or an injured officer as of 1:30 p.m.; Market Street was temporarily shut down due to the incident, but traffic was moving through as of 1:50 p.m.

Allison confirmed that a use of force investigation will be conducted, and that BART investigators are reviewing video of the incident.

On Aug. 1, San Francisco officers shot a dog blocks away after the dog advanced on an officer, police said. The dog was euthanized.
