LITTLE ROCK — A Jacksonville Air Force officer has been indicted on charges of possessing and distributing child pornography, the U.S. attorney’s office said Thursday.

A federal grand jury indicted Shane Padilla, 30, an Air Force captain, on Wednesday on one count of possession of child pornography and one count of distribution of child pornography, said Christopher Thyer, U.S. attorney for the Eastern District of Arkansas.

Padilla was arrested April 4 and released after an April 8 bond hearing. He has been under home detention since his release and is not allowed to have Internet access or contact with minors, Thyer said.

Padilla also surrendered his passport and pilot’s license.

Thyer said the investigation began in May 2013 as part of a larger investigation conducted by Homeland Security Investigation agents in Savannah, Ga.

The agents notified HSI agents in Little Rock that Padilla, who was stationed at the Little Rock Air Force Base, had received child pornography at his email account. Investigators seized electronic devices from Padilla and allegedly found more than 1,000 images and videos of child pornography on them.

If convicted, Padilla could be sentenced to up to 20 years in prison and fined up to $250,000 on each count.
