JAKARTA: Indonesian police said they have arrested two more suspected militants including a member of China’s ethnic Uighur minority who was allegedly preparing to be a suicide bomber.

National Police spokesman Maj. Gen. Anton Charliyan says the suspects were captured in two places Wednesday in Bekasi, a West Java town bordering eastern Jakarta.

The arrests of Arif Hidayatullah, alias Abu Mush’ab, and Alli, a Uighur who used a fake identity card, came as security has been stepped up after officials described a credible threat of attacks, especially against minority Christians, during the year-end holidays.

The government has deployed 150,000 security personnel to safeguard churches, airports and other public places across this predominantly Muslim nation.

At the same time 1,300 security personnel are hunting Indonesia’s most wanted militant, Abu Wardah Santoso, who has pledged allegiance to the Daesh group. The leader of the East Indonesia Mujahidin is hiding in Central Sulawesi. More than 800 Indonesians are believed to have joined Daesh in Syria or Iraq.

“Learning from history, we have to be alert against terrorism,” Charliyan said. “Threats from terrorists could not be ignored.”

Hidayatullah, an employee at a private auto company, was nabbed Wednesday morning while on way to his office. Evidence police said they confiscated included a list of militants who are in prisons and others who are fighting with Daesh in Syria.

Police say he confessed he was ordered by Bahrunnaim, another militant who is now in Syria, to act as a coordinator or facilitator for Indonesians wanting to join Daesh.
