Three women entered the store at 11:30 a.m. Saturday and picked up 150 bras worth $8,000, KIRO-TV, Seattle, said.
The manager followed the women and tried to stop them outside of the store's entrance, but the women attacked the manager.
Police said two of the women punched the manager in the face, and the other woman sprayed the manager with an unknown substance.
The manager was treated at the scene for facial bruising and swelling, KIRO-TV reported.
