The Honolulu Police Department is asking for help locating one of its own officers who is a suspect in a first-degree sexual assault investigation.

Police said in a news release Wednesday that off-duty Officer Jessie Laconsay may be driving a white Dodge Charger. They say he's not believed to be armed.

Officers say Laconsay is known to frequent the Ewa Beach and Kapolei areas. Anyone with information is asked to call 911 or Crime Stoppers.

A phone call to the union that represents Honolulu police was not immediately returned. Police say the license plate number for the Dodge Charger is SVD 631.
