MANILA -- More cocaine packages were found floating in the sea, this time off Caraga town in Davao Oriental on Sunday, authorities said Monday.

Thirty-six bricks containing the cocaine were discovered after they got tangled in the net of 2 fishermen in Barangay Santiago, said the town's police chief, Senior Insp. Fidelito Viola.

A test confirmed that the contents were cocaine, estimated to be worth P200 million, he said.

Dozens of similar drug bricks worth millions of pesos were also found earlier this month in Dinagat and Siargao islands, and in Surigao Del Sur, Camarines Norte and Quezon provinces.

Drug syndicates may be using the Philippines as a "transshipment point" for cocaine, which is repacked here before it is sent to Hong Kong, Taiwan, China and other nearby countries, said PDEA Director General Aaron Aquino.

The floating cocaine packages, however, could also be a diversionary tactic to smuggle tons of meth or shabu into the country, he said.

Authorities earlier promised a sack of rice or P2,000 for every brick of floating cocaine that the public will surrender.

Law enforcement agencies were set to hold a press conference about the drug packages on Monday.
