It was in January 2017, Hafiz Saeed was arrested in Pakistan and was kept under house arrest.
India accused Pakistan of helping organize the attacks in cooperation with Saeed, who is head of the Jamaat-ud-Dawa (JuD) charity, which US officials say is a front for the banned Pakistan-based Lashkar-e-Taiba militant group.
India has also said there is proof that "official agencies" in Pakistan were involved in plotting the attack-a charge Islamabad denies. "I was detained on the pressure of the United States on the Pakistani government".
The MEA Spokesperson informed that external affairs minister Sushma Swaraj will be representing India at the SCO summit in Sochi on 30th November and 1st December.
Several JuD supporters, gathered outside Saeed's house in Lahore's Jauhar town to celebrate his release, shouted anti- India slogans.
Punjab Assistant Advocate General Sattar Sahil said the government law officer had presented "some important evidence" to justify Saeeds detention but all three members of the board unanimously rejected it and ordered his release.
"I fight the case of Kashmiris".
Saeed said later in a video message that he was detained because of his association with Kashmir.
Saeed has long campaigned in support of Muslim separatists in the Indian state of Jammu and Kashmir, to which Pakistan also lays claim.
In previous proceedings, the Punjab Home Department argued that that if Saeed was freed, his activities would pose a serious threat to public safety and public order.
Pakistan often says India is violating human rights in Kashmir, where security forces have killed or wounded dozens of protesters at anti-India rallies in recent months. "The US did so on the request of India", he claimed.
A Pakistan court on Wednesday ordered the release of Lashkar-e-Taiba (LeT) founder Hafiz Saeed, blamed for the horrific 2008 Mumbai terror attack, from house arrest that began in January this year.
Delivering his first "sermon" in over 10 months, the UN-designated worldwide terrorist continued his rant against India and warned that his fight for a "free Kashmir" would continue. Pakistan's Punjab government however had sought a three-month extension in his detention saying that the country may face worldwide sanctions if the JuD was released from house arrest.
Saeed has been declared a global terrorist by the United Nations and the USA for his role in the Mumbai attack which claimed the lives of 166 people and maimed over 300 others.
