Hafiz Mohammed Saeed — the leader of Pakistan’s Jamaat-Ud-Dawa (JUD) — was detained in Punjab, Pakistan’s largest province, according to a government statement released late Sunday.

Saeed is under detention in the town of Lahore. Four other men — Abdullah Ubaid, Zafar Iqbal, Abdur Rehman Abid and Qazi Kashif Niaz — have also been placed under house arrest in other towns around Punjab.

The arrests come in conjunction with the placing of two organizations — JUD and the Falah-e-Insaniat Foundation — on a watch list under Pakistan’s Anti-Terrorism Act 1997.

All the men were detained for being active members of the organizations and are being held under Section 11-EEE of the Anti-Terrorism Act, which gives the government the power to arrest or detain suspects for up to 12 months.
