Even as the Punjab Police maintained that some leads were being investigated, Punjab Chief Minister Amarinder Singh on Monday said the grenade attack on a religious congregation of the Nirankari sect was a clear case of terrorism and there was no religious connection to it.

"It is a clear case of terrorism. This has been carried out to create panic. There is no religious link to it," Amarinder, who visited the grenade attack spot at Nirankari Satsang Bhawan in Adliwal village near Rajasansi, told the media.
