National police spokesman Col. Boy Rafli Amar said Saturday that Imam Firdaus was arrested a day earlier in Jakarta and was recruited into the group to film and broadcast its terrorist acts.

Arya Sinulingga, news director of the Jakarta-based Global-TV, confirmed Firdaus worked there and expressed remorse over the involvement of media employees in terrorism.

The 20 people arrested this week are suspected in Islamic militant plots to bomb a church ahead of Easter Celebrations and sending mail bombs last month.

Police found the bomb placed near a church after the arrests. Only one of the mail bombs exploded, wounding four people.
