The Punjab Police have detained a few people having links to separatist organisations in connection with Sunday-s grenade attack on a prayer meeting of the Nirankari sect in Amritsar, police sources said on Tuesday.

The Sikh hardliner elements were detained in raids conducted by various teams of the state police at different places, including in Amritsar and Bathinda districts. The police have not, however, officially confirmed or denied the detentions.
