ISLAMABAD (Reuters) – Pakistani police detained 30 suspected members of the outlawed Islamic organisation Hizb ut-Tahrir on Saturday in a raid on a house in the capital, a police officer said.

“They were holding a secret meeting in the house. We’re investigating,” said Islamabad police officer Afzal Shah.

The London-based Hizb ut-Tahrir seeks to unite Muslims in a pan-Islamic state but says its means are peaceful.

Former Pakistani president Pervez Musharraf banned the group several years ago.
