Hailing the decision to hang parliament attack convict Afzal Guru, Bollywood megastar Amitabh Bachchan said Saturday that it was important to follow law and order.

"The law should be followed and respected by one and all. Whatever has been done, it has been done according to the law - whoever the accused may be - you, me or someone else," the 70-year-old told reporters at his office.

"The country investigated the matter completely, and only then they have acted as per law," he added.

Afzal Guru was convicted for his role for the attack on Indian Parliament in 2001.
