A Weeksville Elementary School teacher's aide who was arrested three weeks ago by the FBI for allegedly possessing child pornography is now facing additional charges.

Investigators say Taleek Brooks was not only distributing child porn online, but also producing sexually explicit videos involving children. Investigators working on the case say some of the videos may have even been taken on school grounds.

"My personal reaction is one of disgust on the part of this individual," said New York City Schools Chancellor Dennis Walcott, who visited the school Tuesday afternoon. "Based on the initial reports, this is something that is horrendous and we should not tolerate this in our society, much less have an individual like this out on the streets."

The school will be providing crisis counseling and has asked any families with information on Brooks to contact the FBI. If convicted, Brooks faces anywhere from five to 15 years in prison.
