SAN FRANCISCO (CBS SF) — A pet dog snatched by a supposed Good Samaritan from an injured victim involved in a multi-vehicle crash on Bay Bridge last weekend has now been recovered by the California Highway Patrol, authorities said.

In a Sunday Facebook post, the CHP asked the public’s assistance in providing any video/dash camera footage if they were driving in the area at the time of the March 13 collision.

The CHP said that following the crash, a red-colored Scion XB, with Oregon license plates, stopped at the scene to “check on the welfare” of those involved in the collision.

While in contact with an injured crash victim, a man from the Scion snatched a white, one-year-old terrier from the Acura and placed it in the Scion and fled the scene before CHP officers arrived.

The vehicle was tracked down by investigating officers to a San Francisco address where the missing terrier was located and ultimately returned to its rightful owner. The Scion owner was being uncooperative in the investigation and the CHP was hoping a passing motorist may have captured an image of him at the crash scene.
