Lahore, July 28 - A defiant Pakistan said Tuesday it would not arrest Jamaat-ud Dawa (JuD) chief Hafiz Saeed, named by India as the mastermind of the 26/11 Mumbai terror attacks, till adequate proof was provided of his involvement in the carnage.

'We cannot arrest him till adequate proof is provided. There is no proof,' Interior Minister Rehman Malik told a private TV news channel in an interview.

The latest flip-flop comes 12 days after Indian Prime Minister Manmohan Singh said July 16 his Pakistani counterpart Yousuf Raza Gilani had informed him that 'common consensus' was being evolved and that 'action will have to be taken against him (Saeed)'.

Two days before that, on July 14, Pakistan's Punjab provincial government had disassociated itself from the case against Saeed, saying the federal government had not furnished 'solid evidence' to warrant his continued house arrest.

The Punjab government's move came as a three-member Supreme Court bench headed by Chief Justice Iftikhar Muhammad Chaudhry was considering two identical petitions filed by the federal and provincial governments against Saeed's June 2 release by the Lahore High Court.

Punjab Advocate General Raza Farooq told the court that the provincial government had put Saeed under house arrest on the directive of the federal government.

Saeed is the founder of the Laskhar-e-Taiba (LeT) terror group that New Delhi accuses of also staging the Dec 13, 2001 attack on the Indian parliament. The LeT had morphed into the JuD after it was banned in the aftermath of the attack.
