A third member of the U.S. Navy has pleaded guilty in a multimillion-dollar bribery investigation involving a Singapore-based defense contractor charged with providing cash, vacations, electronics and prostitutes in exchange for classified information.

Daniel Layug entered his plea Tuesday in San Diego to one count of conspiracy to commit bribery.

The 27-year-old petty officer admits providing classified shipping schedules and other internal Navy information to the contractor in exchange for $1,000 a month, a digital camera and other consumer electronics and travel, including hotel stays in Malaysia, Singapore and Indonesia.

Layug was stationed as a logistics specialist at a Navy facility in Yokosuka, Japan.

The investigation centers on Leonard Glenn Francis and his company known as GDMA. Francis was arrested in September and has pleaded not guilty in the case.
