MILWAUKIE, Ore. -- Gym members are being warned of a man with a knife who mugged a woman.
Clackamas County sheriff's deputies say the attack happened around 7a.m. Friday in the parking lot of the East Side Athletic Club in unincorporated Milwaukie.
Investigators believe the suspect targeted the parking lot because there was a lot of activity and people are distracted while getting gym bags out of their cars.
The victim was not hurt but shaken up, according to deputies. They would not say what was taken during the robbery, but witnesses told KATU News that he got away with a purse and the woman's cellphone.
The crime happened in under a minute.
Investigators are looking at surveillance video from a nearby business to help find the suspect.
The victim described him as Caucasian, in his 30s and about 5 feet 10 inches tall with a thin build. He was last seen wearing a black jacket and jeans. Call police if you have any information.
