ZAMBOANGA CITY, Philippines — The National Bureau of Investigation is investigating how boxes of dried seahorse worth millions of pesos disappeared from the storage warehouse of the Bureau of Customs.

Lawyer Lyceo Martinez, BOC district collector, said he asked the NBI to conduct an investigation after he learned last week that seven boxes of the contraband had gone missing.

Martinez said the seven missing boxes were part of 15 boxes of dried seahorse that were intercepted and seized by the Coast Guard after an attempt to slip the shipment to Manila in early August.

The entire shipment is valued at P5.2 million and the missing boxes are worth around P2 million. According to an earlier report, the contraband was valued at P5.7 million.

"I wrote a letter to the NBI to conduct an in-depth and all-out investigation," Martinez said.

He said an initial investigation by port police investigation found that the boxes may have been slipped out of the warehouse through the ceiling.

"However, I leave it to the NBI to determine if that was possible," Martinez said.

He said if the NBI finds the theft was an inside job, he will not hesitate to file charges against those involved.

"I will let [any] involved employees face the full force of the laws," he also said.
