Officials said the four – Nasser Asiri, Hajad Namli, Musimar Ismael and Umra Jawadi – were captured after police forces raided their hideout in the town of Maimbung on Thursday.
Police said the four men admitted killing Willie Mar Ajijul, 40, after stealing his motorcycle in Indanan town. The town’s police chief, Inspector Amil Baanan, also joined in the operation that led to the capture of the four.
“We are still investigating the four men and whether they have links with the Abu Sayyaf or plain criminals,” said Sulu police chief, Senior Superintendent Muhimuddin Ismail, who led the operations in Maimbung, after citizens tipped off the authorities about the suspects.
The Abu Sayyaf has previously used motorcycles rigged with explosives in its reign of terror in Sulu and Zamboanga City. (With a report from Nickee Butlangan)
