A man suspected of posing as a police detective and telling an adult novelty shop to give him free X-rated videos so he could check for underage performers was arrested Tuesday, authorities said.

Drew Libby, 33, was arrested on suspicion of impersonating an officer, possession of an illegal weapon and possession of marijuana and drug paraphernalia.

Investigators said they believe Libby made three unsuccessful attempts to get free videos from the store, showing a badge and leaving a business card from the Longmont police "age verification unit." There is no such unit, police said.

Libby was identified by a police officer and tipsters after photos were distributed from a surveillance camera in the store.

No phone listing could be found for Libby. Boulder County Jail does not know if he has an attorney.
