A Gainesville man is accused of having photos of underage girls, according to authorities.

Phillippus Rudolph Uys, 56, of Gainesville, is charged with child exploitation. He was booked Thursday into the Hall County Jail, where he remains.

According to the Hall County Sheriff’s Office, Uys allegedly had in his possession photos “of females under the age of 18, engaged in lewd exposure and sexual activity.”

Uys also has an immigration hold.

“We have a couple of investigators who work these types of things and get alerted when people are downloading or sharing videos or images,” Lt. Scott Ware said. “At the point that that occurred, investigations were initiated.”

The case is still under investigation by the sheriff’s office.
