Pittsburgh Police from Zone 4 were dispatched to the 5400 block of Walnut Street for reports of a robbery and assault behind a business just before 9:30 p.m.
A male reported leaving through the back of the restaurant where he works when he was approached by three males wearing masks who beat him and stole $200 and his cell phone.
Medics treated the victim on scene for a laceration to his head, but he refused transport to the hospital.
He told police he believes the actors fled in an older model, dark-colored Honda CRV.
The investigation is ongoing.
