An Arlington youth group leader is accused of using a popular chat app to share child pornography.

Andy Matthew Haas, 24, was charged with child exploitation after authorities said he used the messaging app Kik to share explicit images of prepubescent boys, according to Erin Nealy Cox, U.S. attorney for the Northern District of Texas.

Kik flagged the images as having data characteristics linked to known child pornography and reported them to law enforcement. Agents then traced the IP address associated with the upload to Haas.

Haas, a computer programmer, admitted under questioning that he had shared close to 100 pornographic images of children, some as young as 8 or 9, that he had gotten from Kik group chats over the past two years, officials said.

If convicted, Haas faced up to 20 years in federal prison.

Authorities did not say what church Haas was associated with.
