BISMARCK, N.D. (AP) — Authorities say a Mandan man charged in a prostitution sting last spring is accused of trying to lure a minor girl for sex this week.

Court records say 42-year-old Michael Keller communicated online with an undercover Bismarck police officer posing as a 15-year-old girl. Prosecutors say Keller arranged to meet the girl in a parking lot after school Monday, but was met instead by police.

Keller is on probation after pleading guilty in July to prostitution charges. He was one of 18 men arrested last May in a prostitution sting. He received a suspended jail sentence.

The Bismarck Tribune says a judge has set bond at $1,000 for Keller who's now facing a felony charge of using a computer to lure a minor. Court records do not list an attorney for Keller.
