The Pakistani courts have been ordering Lakhvi in and out jail since December, though he has remained in the Rawalpindi prison during all this time. Most recently, he was granted bail and put under detention last month, which upset India greatly. His release will do the same.
Pakistan has stated that his incarceration is illegal without proper evidence, and has asked India to submit the necessary documents which would keep him in prison. In response, Indian officials said they have provided all that is necessary, including voice samples and witness statements. They have also said that it is up to them to ensure that Lakhvi remains in jail.
In 2008, 166 people were killed and 300 injured in a coordinated attack in Mumbai. Six others have also been arrested in connection with the attack, but Lakhvi is believed to be the mastermind behind it all.
