Three employees of a Japan Airlines Corp. cleaning subsidiary are suspected of stealing digital cameras and other items left on planes by passengers, aviation industry sources said Wednesday.

The employees, aged between 19 and 21, have admitted engaging in theft to police, the sources said. They are employed by JAL Ground Air Service Co., which is tasked with cleaning aircraft.

The men allegedly stole two digital cameras, an iPod music player and a Nintendo DS game console between April and November last year.

Some of the items were stolen when discovered aboard the planes while cleaning, but others were stolen from a lost and found storage facility.
