ASHWAUBENON - Authorities have arrested a 20th suspect in an Internet sex sting.
Ashwaubenon Public Safety officials say the 37-year-old De Pere man had an online conversation with officers posing as a 15-year-old girl. He was arrested at an Ashwaubenon coffee shop, where he thought he was going to pick up the girl to take her back to his home for sex.
The man is the 20th arrested in Operation Vanguard, a coordinated effort among Northeast Wisconsin police agencies which took place last Thursday through Saturday.
The man has not been formally charged in the case.
