Coast guard spokesman Lt. Cmdr. Algier Ricafrente says the Hong Kong Maritime Rescue Coordinating Center reported late Friday that it had received a distress call from the MV Oceanic Union off Ilocos Norte province.

He says the ship may have sunk or was sinking since the crew had already abandoned ship.

A navy vessel and a coast guard vessel, helicopter and airplane are scouring the waters about 100 miles (160 kilometers) west of Burgos township. Other ships passing through the area have been notified.

The Panamanian-registered ship was heading to Subic Bay west of Manila from Shanghai.
