A math teacher and coach at Cloonan Middle School turned himself in on Friday in connection to a child pornography investigation that began in August, police say.

Gregory Kelly, of Stamford, has been on administrative leave since police developed him as a suspect in their investigation.

Police say they found 150 pornographic images on approximately 30 seized devices. Police say they also discovered two voyeuristic videos involving two teenage female victims.

"One of the videos was in the home of Mr. Kelley and the other one was in the home of one of the victims," said Lt. Tom Scanlon, of the Stamford Police Department.

Stamford Public Schools told News 12 that Kelly has not been in a classroom since August and that the district has been cooperative in the investigation.

Kelly faces multiple child pornography charges, including two counts of voyeurism. His bond was set at $500,000.
