Alameda County Sheriff’s Sgt. J.D. Nelson said Gimbert was arrested on the last day of the fair in Pleasanton on suspicion of using misrepresentation to solicit a person into a life of prostitution.

“What he would do is he would see girls and he would talk to them and then hand them a card that basically says if they turn 18 that they’d get a signing bonus and it had pictures of topless women on it,” Nelson said.

The cards with the words “Big Pimpin Inc.” offered a $1,000 sign-on bonus for an 18th birthday contract.

Nelson said members of the Sexual Assault Felony Enforcement or SAFE task force were at the fair and observed Gimbert hand out a card to at least one underage teenage girl on Saturday and another on Sunday.

“He was basically a contractor to one of the games. He’s not affiliated with the fair or the carnival even, but he’s one of the game operators,” Nelson said.
