A man assaulted a bikini barista in Kent, Washington, and attempted to rape her after buying a drink early Tuesday morning, according to police.

At 4:45 a.m., police responded to the Hottie Shots Espresso stand after a 30-year-old barista reported the incident.

The barista, a Bonney Lake, Washington resident, told police that the assailant came to the coffee stand window on foot and ordered a drink. While the barista was making the drink, investigators say the assailant climbed through the window and held her at knifepoint.

Police say that during the assailant's attempt to sexually assault the barista, he noticed vehicle headlights of a customer pulling into the drive-thru and fled the area.
