Police have arrested three people, saying they attacked a Pennsylvania mall employee on Tuesday, stole her SUV and led police on a chase that ended in a crash with a public bus.

Upper Merion Township Police said about 9:45 p.m. on Tuesday, the mall employee was walking to her SUV in a lower level parking lot at the King of Prussia Mall when a 17-year-old man, accompanied by a 17-year-old woman and a 14-year-old girl, asked to borrow her phone.

The young man handed the worker’s phone to one of the other teens, then grabbed her from behind, “placing her in a chokehold,” police said. Police also said one of the girls punched the employee and threw her to the ground.
