A sex offender, on probation for conduct with and exploitation of a minor, has been arrested again on child-sex charges, Tucson police said Tuesday.
Jacob T. Osterkamp, 28, of the 11400 block of West Green Desert Road was being held in the Pima County Jail in lieu of $25,000 bail on a charge of attempting to lure a minor for sexual exploitation, police and jail authorities said.
He also was being held without bail on probation violation charges in connection with earlier convictions in Tucson for sexual conduct with a minor and for sexual exploitation of a minor, a jail clerk said.
Osterkamp is listed on the state Department of Public Safety’s sex offender Web site.
Police began their investigation May 1 when a woman reported unsolicited, obscene text messages, police spokesman Sgt. Fabian Pacheco said.
The woman told police the man texted that he was looking for a friend and asked if the recipient was a man or a woman.
The woman, who has teenage children, replied that she was a minor. Soon, she began getting messages of a sexual nature, Pacheco said in a news statement. The man gave his age and asked the recipient to meet him.
Detectives used the woman’s cell phone to text message the suspect. Detectives also got a subpoena for the man’s cell phone and identified him as Osterkamp.
Wednesday, Osterkamp was arrested at his home and booked into jail, Pacheco said.
