SAN ANTONIO -

A city of San Antonio employee is facing federal charges after a grand jury indicted him for allegedly distributing child pornography.

According to the Dallas office of the FBI, Philip Branson was caught using peer-to-peer software to share images of minors involved in sexual activity and sexually explicit poses.

According to the City of San Antonio website and Branson's own LinkedIn profile, he works for the city's Capital Improvements Management Services division where he is a capital programs manager.

According to a federal grand jury indictment, Branson allegedly used the software and the internet to share at least four images depicting a prepubescent male and prepubescent girls engaging in sexually explicit conduct.

Branson is accused of sharing the images over the internet in May 2012.

According to his LinkedIn account, Branson was overseeing the $325 million addition and expansion and renovation of the Henry B. Gonzalez Convention Center.

The indictment shows the FBI seized an 8-gigabyte thumb drive and a 500-gigabyte external hard drive as part of their investigation.

If convicted, Branson faces five to 20 years in federal prison and a $250,000 fine.

At this point it's unknown when Branson was taken into federal custody or when he'll be back in court to face these charges.

On Tuesday afternoon, a representative for the city issued this statement:

"On Tuesday, January 28, the FBI arrested Philip Branson. Mr. Branson was a Project Manager in the Transportation & Capital Improvements Department on the Henry B. Gonzalez Convention Center Expansion Project. Effective immediately, Mr. Branson no longer works for the City of San Antonio. Mr. Branson’s duties are now being handled  by Assistant Director of Transportation & Capital Improvements, Razi Hosseini. The Convention Center Expansion project continues to be on schedule and under budget."
