When a Spokane drugstore clerk confronted a suspected shoplifter early Friday he pulled out a knife and threatened her.

Police say the Walgreens clerk punched the man in the face and knocked him down. He dropped the knife. She picked it up, and he ran off.

Police found a suspect in the area wearing a black stocking cap with tassels that had been shoplifted.

The 25-year-old was identified by the clerk and jailed for investigation of robbery.
