LOS ANGELES — It was another routine night at a Nordstrom’s Rack at a Los Angeles mall until two armed robbers stormed inside as the workers prepared to go home.

The men took 14 employees hostage late Thursday, stabbing one and sexually assaulting another before escaping during a three-hour standoff with police.

The store remained closed Friday as investigators looked for the suspects and interviewed the traumatized employees at the store near Los Angeles International Airport.

Police responded about 11 p.m., when a man phoned 911 and reported that his girlfriend had called to say gunmen were in the store, police Lt. Andy Neiman said.

“She told him, ‘Call 911. Two guys with guns just came into our store,’ ” Neiman said.

Police officers and special weapons team members swarmed the outdoor shopping center that also has restaurants and a theater.
