BANGKOK--“Luffy,” the suspected mastermind behind a string of robberies in Japan, including Tokyo, has been detained at an Immigration Bureau facility in Manila, authorities in the Philippines said Jan. 27.

The suspect’s real name was not released.

The authorities said procedures are being taken to deport the man to Japan. He is currently prohibited from using communication devices in the detention facility.

Another Japanese national believed to be part of the burglary ring has also been detained in the Philippines, they said.

After police in Japan analyzed records of phones seized from suspects arrested in connection to violent robberies, they found that a person using the name Luffy provided instructions from the Philippines.

The country code for the Philippines was found in the phone number used by Luffy.
