Police in Arlington arrested a D.C. resident Sunday after he allegedly groped a female customer at the Whole Foods supermarket on Wilson Boulevard in Clarendon.

The assault happened about 1:50 p.m., when the victim bent down to grab a bottle of wine from a grocery display and the suspect stuck his hand between her legs and on her genitalia, police said.

A suspect was found about four hours later after being located sleeping on a nearby park bench with several pornographic magazines among his belongings, police said.

At police headquarters, things got even creepier, according to a police report. As officers began questioning him, the suspect, Frank Alex Bouknight, repeatedly began masturbating, police said. Bouknight, a 24-year-old District resident, was arrested on sexual battery charges.
