Pakistani federal government filed a petition on Saturday in the Supreme Court of Pakistan to challenge the release of the outlawed group Jamaat-ud-Dawa (JuD) chief Hafiz Saeed, according to the Express TV channel.

Local media quoted Attorney Latif Khosa as saying that there were "sufficient grounds" to challenge the Lahore High Court (LHC)verdict that set Hafiz Saeed free.

LHC released Saeed on June 2 who was detained last December after the United Nations declared JuD, a frontal organization of the Lashkar-e-Taiba (LeT), as a terrorist group.

Saeed was put under house arrest in Lahore last December in the wake of the Mumbai attacks in India, which left around 170 people dead. The LHC insisted that there was no sufficient ground to detain or link Saeed to the Mumbai terror attacks.

India claimed that Lashkar-e-Taiba was behind the Mumbai attack and the Pakistani government started to crack down on JuD last December.
