The FBI is asking for the public's help in identifying a man who can be seen on video sexually abusing a child.

The man is known only as John Doe 28. He was first seen on video performing sex acts with children in November of 2012. Agents say there are several clues in the images that may help them locate him. The video shows the man and his victim inside a residence with what appears to be a blue sofa chair and a picture hanging on a wall in the background. Additionally, the subject is wearing wire-framed glasses and a burgundy t-shirt with what appears to be a shark logo on his left side. He is a white man, possibly in his 30's or 40's, with a receding hairline.

There is nothing that ties the man to a particular state or region in the United States.

The search for John Doe 28 is part of Operation Rescue Me and the Endangered Child Alert program. The programs focus on identifying both victims and suspects seen in child exploitation videos and images.

The man's image will be sent out all over the country, in hopes that someone can identify him. If you have any information, call 1-800-CALL-FBI.
