India expresses concern over Lakhvi walking out of Pakistan jail

"Our concerns on this issue have been made known to the Government of Pakistan in the past. These shall be reiterated. The fact is that known terrorists not being effectively prosecuted constitutes a real security threat for India and the world," said a Ministry of External Affairs spokesperson on Thursday.

"This also erodes the value of assurances repeatedly conveyed to us with regard to cross border terrorism," he said.

The Lahore High Court has declared the detention of 26/11 Mumbai attack plotter Zaki-ur-Rehman Lakhvi in a Pakistan jail as illegal. He might get a release soon, said media reports in Pakistan on Thursday.

Reports said the court asked him to pay a surety bond for his release.

Earlier Pakistan had assured India that  Lakhvi they would ensure that he stays in jail.

The Islamabad High Court acquitted Lakhvi earlier evoking strong protests from India.

The court said there is no such evidence against Lakhvi to keep him in jail.

However, after India took up the matter at the highest level, the Punjab state government of Pakistan slapped fresh charges on Lakhvi which are supposed to keep him in detention for some more time.

The 2008 Mumbai attacks were twelve coordinated shooting and bombing attacks across Mumbai by members of Lashkar-e-Taiba (LeT).

The attacks, which drew widespread global condemnation, began on Wednesday, Nov 26, 2008 and lasted until Saturday, Nov 29, 2008, killing 164 people and wounding at least 308.

Eight of the attacks occurred in South Mumbai - at Chhatrapati Shivaji Terminus, the Oberoi Trident, the Taj Mahal Palace & Tower, Leopold Cafe, Cama Hospital (a women and children's hospital), the Nariman House Jewish community centre, the Metro Cinema, and a lane behind the Times of India building and St. Xavier's College.

There was also an explosion at Mazagaon, in Mumbai's port area, and in a taxi at Vile Parle.
