New Delhi, Aug 26 - Stepping up pressure on Pakistan over Hafiz Saaed, India Wednesday said the Interpol red corner notice against him vindicated its stand on his involvement in Mumbai terror attacks and asked Islamabad to take action against him.

'Interpol has issued Red Corner Notice for Saeed's involvement... It is a vindication of the stand the government of India has taken,' External Affairs Minister S.M. Krishna said here.

The world should take note of the Interpol notice and come to their own conclusions, he said.

'The perpetrators of the Mumbai attacks will have to be brought to justice. We have painstakingly collected evidence to convey the involvement of these persons,' he said.

Saeed heads the Jamaat-ud-Dawa, a front organisation of the LeT blamed by India for the attacks.

Pakistan is now duty bound to arrest Saeed, CBI spokesperson Harsh Bahl told IANS. 'It is an administrative procedure and Pakistan is now obliged to arrest Hafiz Saeed and hand him to India for trial in the Mumbai attacks.'

The red corner notice on Tuesday night followed the non-bailable arrest warrants by a special court in Mumbai against Saeed, Lakhvi and 20 others for their alleged roles in the 26/11 attacks.
