The Philippines is seeking to have local criminal charges against some of the four Japanese believed to be behind a string of robberies across Japan dismissed, a Justice Department spokesman said Wednesday, as the Southeast Asian country seeks to deport all four to Japan.

The pending charges have left it unclear whether the suspects can all be swiftly transferred to Japan from the immigration facility in Manila where they are being held.

Court hearings have been planned for Thursday and Friday based on a motion filed by the department, and there is a possibility that the court will drop the charges, the spokesman said.
