A police source says Greek police have detained four suspected terrorists, including one who could be the man wanted by Belgian authorities as an alleged ringleader of a jihadi cell.

The source spoke on condition of anonymity because the person was not officially authorized to comment on an ongoing investigation.

The person said the four were arrested Saturday, including one who "matches the description" of Abdelhamid Abaaoud — the man who Belgian authorities suspect was the mastermind behind a dismantled jihadi cell there.

Greek police have sent photos, fingerprints and DNA material to Belgium and are waiting to see whether the person is indeed Abaaoud, the source said.
