ZAMBOANGA, Philippines – Security forces on Sunday (June 22nd) captured four Abu Sayyaf members in Mindanao, including one accused in the 2002 kidnapping of Christian missionaries who were later beheaded, AFP reported.

Three of the four were arrested in a coastal village near Zamboanga on Sunday night, city police chief Angelito Casimiro said.

"We recovered from them documents of a plan to kidnap a local businessman and a son of a shipyard owner," Casimiro said.

The fourth, Sattar Sabtula, was arrested earlier that day by combined military and police intelligence units. Sabtula was allegedly involved in the 2002 kidnapping of a group of Jehovah's Witness missionaries on Jolo, Casimiro said.

Two were beheaded; four others were freed after months in captivity, following ransom payments, police said.
