Indonesian police yesterday arrested six people suspected to be behind a series of recent parcel-bombs in Jakarta, they said, as another device was found near a church in the morning.
"We arrested six people at 5:10 am," national police spokesman Anton Bachrul Alam told reporters.
"We're still investigating their possible links with terror groups," he said.
The men, held in anti-terror raids on two rented houses in East Jakarta, were believed to be connected to mysterious deliveries of bombs hidden in hollowed-out books last month, an unnamed police source told AFP.
The "book bombs" were sent to several addresses including those of liberal Muslim figures and a counter-terrorism official, but no one was killed.
