Three home-made bombs went off in Indonesia's West Java province, before they were used for planned attacks, police said on Saturday.

Deputy Chief of National Police Commissioner General Syafruddin said militants had plotted to launch attacks at a church, a restaurant and a cafe in Bandung city, the provincial capital of West Java.

"The targets were Cafe Bali on Braga street, Celengan restaurant in Astana Anyar and Buah Batu church," he was quoted by the local Metro TV as saying.

However, the bombs exploded before they were planted, according to him.

The pressure cooker bombs exploded in a rental house in Kampung Kubang of Buah Batu sub-district at about 3:30 p.m. local time (0830 GMT) on Saturday, but did not leave any casualties, Syafruddin said.

The police arrested an alleged assembler of the home-made bombs who has initials of AW, he said, adding that the 22-year-old suspect learned to make bombs on the Internet.
