A pizza delivery man was believed to be pepper sprayed in Cambridge on Saturday, according to police.

Police say he was making a delivery on Alison Avenue around 2:30 a.m. Saturday morning when two men approached him from behind and sprayed him in the face.

Police say they then stole his cell phone, car keys and the pizza.

Police are looking for the attackers, who were wearing black winter clothing.

One of the suspects had a ski mask on.

Investigators are still trying to determine if the delivery man was lured to the building by his attackers.
