Jhang, Pakistan - Pakistani authorities have closed down the offices of 16 publications run by followers of the Qadiani sect in the central Punjab city of Jhang.
Two printing presses were sealed and cases registered against editors and publishers for "propagation of offensive material", police said.
At least two people were arrested and raids are continuing.
Qadianis, also known as the Ahmadiyya, were declared non-Muslims under the constitution in 1974.
The sect was founded by Hadhrat Mirza Ghulam, who was born in the town of Qadian in Punjab in 1835.
The Qadianis believe he was the Imam Mahdi, or the Promised Messiah.
Jhang police chief, Hamid Mukhtar Gondal, told the BBC the action had been taken on orders of the Punjab home department.
He said the 16 publications had already been banned but the Jamaat-e-Ahmadiya - Pakistan's largest Qadiani party - had continued to print and distribute them.
Literature deemed religiously offensive and banned under Pakistani law was recovered from the offices of some of the publications.
The latest action was triggered on a complaint by a local religious leader, Maulana Chinioti, who has been in the forefront of the campaign against the minority sect.
Mr Gondal said he could have charged Qadiani leaders and editors under anti-terrorism laws but had decided not to do so.
"For the time being, we have booked them for propagating material offensive to people of other faiths," he said.
A spokesman of the Jamaat-e-Ahmadiyya told the BBC that none of its publications were offensive and their closure reflected religious prejudice against the community.
The Jamaat-e-Ahmadiya had never been involved in any form of violence or any hate campaign, he said.
"We have in fact always been victims of prejudice," he said.
Mainstream Islam believes Mohammad was the last Prophet.
