Local police, accompanied by state police and Secret Service officers, went to the Westfield home of William Keys on Tuesday to recover a digital camera's memory stick after three photos that appeared on the Internet were tracked to Keys, police said Friday.

Officers then went to Precision Camera and Video Repair in Enfield, Conn., where Keys works, and recovered the camera. It remains in custody of Westfield police.

No one has been arrested or charged in the case. It was unclear who took the photos.

Keys did not return telephone calls Friday.

"It's an ongoing investigation, and we cannot comment," said Jane Robison, a spokeswoman for the Los Angeles County prosecutor's office.
