TAMPA — Do you recognize the man in these images?

On May 2, he appeared online in child porn videos. Authorities say he raped a girl who may be as young as 7.

Federal investigators want to find him, because they hope to rescue the child from ongoing sexual assaults.

The Danish National Police found the four videos, but a U.S. federal agent concluded from unique packaging on a bag of Rold Gold pretzels that the child and the man are in the United States.

But where?

U.S. Immigration and Customs Enforcement asked the public for help Tuesday, releasing a series of partial images of the man, taken from the videos.

"We've had a couple of instances where we've tracked child predators down when we've asked for the public's assistance," said Carissa Cutrelle, a spokeswoman for ICE.

Anyone with information is asked to complete an online tip form at www.ICE.gov/tips or by calling toll-free 1-866-347-2423. The agency says that tips will remain anonymous.

The man has a large paunch and appears to be 45 to 55 years old, balding with a wreath of light brown hair and a brown mustache.

The girl is estimated to be 7 to 9 years old.

The room contains guitars, speakers, a keyboard and other electronic equipment, a musician's stand and stool. In one image, the chair bottom is draped with red-and-white checkered cloth or towel, and there's a pink mat against the back rest.

The date stamps on the videos, if correctly set, show that they were produced on April 14 and April 27.
