Wichita police have arrested a county paramedic who they say possessed pornographic pictures of girls he met through a program for teens interested in becoming EMTs.

Lt. Kevin Vaughn said Monday the 23-year-old Sedgwick County Emergency Medical Service employee was arrested over the weekend. He faces charges of indecent solicitation of a child, sexual exploitation of a child and electronic solicitation.

Vaughn says the illegal activity took place in 2011 and the suspect had photos of the teenage victims on his phone. He tells KAKE-TV the suspect met some of the girls through the county’s Explorer program but didn’t say how many children were involved.

The man has worked for the county since 2010. The county says he has been suspended.
