Vijay Kumar Malhotra, chief whip and spokesman of the Bharatiya Janata Party, said that the twin bomb blasts in two Delhi cinemas on Sunday evening were the handiwork of the Inter-Services Intelligence to defame the Sikh community.

Malhotra told rediff.com that the government should step up vigil and bring the culprits to the book. "The miscreants carefully selected the two theatres where the screening of the film Jo Bole So Nihal was going on. This film is controversial but I do not believe that any Sikh would do this sort of work," he said.

Malhotra condemned the incident and expressed his sympathies for those injured in Satyam [Get Quote] and Liberty cinemas.

Delhi police public relations officer Ravi Pawar denied any deaths. Asked how a private television channel had been saying that three people had died, Pawar said that the channel had earlier put the toll at eight.

"As I speak to you I have no report of the deaths. Investigations in the matter are on," he said.
