Security forces on Saturday took into custody two brothers of Anwaarul Haq, the alleged facilitator of the Feb 13 suicide bombing in Lahore, from their residence in Bajaur Agency of the Federally Administered Tribal Areas (Fata), security sources said.

Punjab Chief Minister Shahbaz Sharif had announced Haq's arrest in a press conference on Friday evening. The suspect's confessional statement was also aired during the briefing.

Acting on information provided by intelligence agencies, security personnel on Saturday raided Haq's house in Mamond tehsil of Bajaur Agency, security sources said.

Haq's two brothers Khalilullah and Hameedullah were taken into custody during the raid.

Several others were nabbed from the area during the operation and shifted to an unknown location for interrogation, the sources added.

In his press conference, the Punjab chief minister claimed to have eliminated the terrorist network involved in Monday’s suicide attack in Lahore in which 15 people were killed.

Shahbaz said the facilitator, Anwaarul Haq, had divulged that their network was operating from within Afghanistan.

The suspect in the confessional video said he hailed from a remote village in Bajaur Agency.

“I was associated with Jamaat-ul-Ahrar and they trained me,” said the suspect, adding that he has visited Afghanistan around 15 to 20 times.
