Advocate Sarfraz Hussain filed the petition in the Lahore High Court (LHC). He said the JuD chief has been put under "illegal" detention by manoeuvring the anti-terrorism law.
"The government has detained Mr Saeed citing a resolution of the United Nations Security Council as he made the Kashmir issue alive. But the UNSC's resolution for plebiscite in the Indian-held Kashmir has not yet been implemented. The government has detained him at the behest of the foreign masters," he said.
An official of Jamaat-Ud-Dawa (JuD) told PTI that Saeed would challenge his detention soon.
"The JuD has nothing to do with advocate Sarfraz Hussain's petition as he has filed the petition on his own," he said.

However, a source in the LHC said Hussain has filed the petition at the behest of JuD.
The LHC will fix the date of hearing later.
The government on Monday placed Saeed and his four accomplices -- Abdullah Ubaid, Zafar Iqbal, Abdur Rehman Abid and Qazi Kashif Niaz -- under house arrest in Lahore.
