Michael Montalvo, 24, a downtown resident, is accused of engaging in sexually charged online chats with what he thought was a 15-year-old girl.

An arrest warrant affidavit stated that in reality, a detective with the San Antonio Police Department’s Vice Unit was on the other end as Montalvo sent pornographic pictures, tried to arrange a meeting for sex, and showed himself engaging in sex acts.

The affidavit stated that Montalvo had been communicating with the officer at least since February.

Police said that’s when he sent 11 pornographic pictures to what he believed was the teenage girl.

Last week, police said, Montalvo activated a web camera and showed himself engaging in a sex act.

They said at one point he asked about meeting for oral sex. Montalvo was booked into the Bexar County Jail Thursday on a charge of online solicitation of a minor.
