Islamabad: A 16-year-old boy wearing a suicide-bomber jacket and carrying a hand grenade was arrested Monday in an army-controlled area in Pakistan's troubled northwest, police said.

Senior police officer Akhtar Ali Shah said the youth was taken into custody on Monday morning at a military cantonment, about 30 miles (45 kilometers) east of Peshawar, the site of a suicide bombing Saturday that killed 35 people.

"Swift action by the police yielded the arrest of the boy, who was brought into the cantonment area by accomplices who are being traced," Shah said.

He said the boy was being interrogated by a joint team of senior investigators from the police and security agencies.

He would not speculate on the possible target but said the army's supply corps is located in the area.
