New Delhi: Pakistan said on Saturday it might seek the custody of Ajmal Amir Kasab, the lone terrorist captured during the Mumbai mayhem, if the move would aid its investigations, but India immediately dismissed the idea.

"The crime was committed in India. There is no question of handing Kasab to them. In fact, Pakistan should hand over to India the other suspects they've arrested because they were responsible for this terror attack. It can't be the other way around," sources in the Indian external affairs ministry said in New Delhi.

Pakistan's suggestion that it might seek custody of Kasab was also criticised by Indian lawyers.

Prominent criminal lawyer Ram Jethmalani called the idea "absurd and childish".

"We are sick of this stupid game played between India and Pakistan. What do they want to achieve? This is absurd and not at all possible," Jethmalani told IANS.

He added that if Kasab was handed over to Pakistan, related evidence would have to accompany him.
