LOS ANGELES, Calif.–Two men held up a 24-hour Subway restaurant in South Los Angeles today and briefly took a woman customer hostage as they used her car to get to their getaway vehicle, police said.

The two robbers held up the Subway on Central Avenue south of Manchester Avenue around 1:30 a.m., said Sgt. James Winter of the Los Angeles Police Department’s Southeast Station. They used an assault rifle, possibly an AK-47, in the heist, he said.

The pair forced a woman customer into her car, Winter said.

“Initially, she drove, then they switched places and they drove,” Winter said.

The robbers left the woman and her car “a few miles away” from the Subway restaurant, he said, adding she was physically unharmed but shaken.

Police believe they know the identities of the two robbers, who remained at large this morning, Winter said.
