A man arrested in May for spying in restrooms at Rangers Ballpark in Arlington is now facing federal charges of child pornography after inappropriate photos of children where discovered on his cell phone.

Arlington police began their investigation May 13 after receiving reports of a man spying in a men's restroom at the stadium.  According to Arlington Police Media Relations Coordinator Tiara Ellis, a man at the ballpark contacted security to report a man watching young boys urinating; the man was also seen walking into several restrooms.  An off-duty Arlington police officer working at the ballpark contacted the suspect, 48-year-old Michael Allen Manske of Hubbard, Texas, and Manske admitted being previously arrested for indecent exposure and being registered as a sex offender.  Manske was arrested when officers discovered an outstanding traffic warrant from Dallas.

While checking Manske's cell phone, investigators found images of young boys at the ballpark; all of the boys were clothed and none were in restrooms.  One image was found of what appeared to be a nude boy; that photo was determined to be taken from the Internet.

Manske later told a Crimes Against Children detective he is sexually attracted to young boys and goes into restrooms to watch them urinate.  As a result of the investigation, three warrants were issued for Manske's arrest for Improper Photography or Visual Recording, a state jail felony; these charges stem from the images of clothed boys; police say those photos were taken at the ballpark in July 2011.

Manske was taken into custody Wednesday, July 18, by the Hill County Sheriff's Department.  Arllington police are working with other local and federal investigations involving Manske.
