( CNN ) Pakistan 's highest court Friday ordered the release of Zaki-ur-Rehman Lakhvi , the alleged mastermind behind the Mumbai attacks , calling his detention illegal . Lakhvi , a top leader of the terrorist group Lashkar-e-Taiba , was not present at Friday 's court proceeding . The terror attacks in India left more than 160 people dead in November 2008 . In the attacks , heavily armed men stormed landmark buildings around Mumbai , including luxury hotels , the city 's historic Victoria Terminus train station and a Jewish cultural center . On Friday , India summoned the Pakistan high commissioner `` to convey our strong feelings about ( the ) Lakhvi verdict , '' said India 's external affairs spokesman Syed Akbaruddin . Last year , the court granted Lakhvi bail , a decision the Pakistani government had said it would challenge . Many in India are still angry over the attacks and had criticized the bail decision . `` It is very disappointing that the accused of the Mumbai attacks has been granted bail , '' the nation 's home minister , Rajnath Singh , said in December . India executed the last surviving gunman from the attacks in 2012 . Other suspects were all killed during the series of attacks , which went on for three days . CNN 's Harmeet Shah Singh contributed to this report .
