Suspected terrorist Muhammad Thoriq, 32, on the run since Wednesday, surrendered himself to the police on Sunday.
Jakarta Police spokesman Sr. Comr. Rikwanto told reporters on Sunday night that Thoriq came to the Jembatan Lima police post in West Jakarta at 5:30 p.m. and surrendered himself.
"He is now being questioned at the Jakarta Police general crimes directorate," Rikwanto said.
Thoriq, a bomb-maker who fled his home in Tambora, West Jakarta, on Wednesday, is believed to be linked to the recent shootings targeting police posts in Surakarta, Central Java.
Thoriq's identity as a bomb-maker was accidentally revealed when his mother split open a container of powder at his home at Gang Terate VII, Jembatan Lima, Tambora. The powder filled the air and caught their neighbors' attention, who thought the house was on fire.
Thoriq managed to escape shortly thereafter as his neighbors broke into the house, leaving his wife, mother and infant son behind.
A police investigation revealed that the powder was an ingredient for making explosives. When raiding the house, police also found other bomb-making materials, such as sulfur, potassium, charcoal, aluminum powder, two boxes of nails, duct tape, four 9-volt batteries, five 25-centimeter pipes filled with explosives, electronic switches and several detonators.
