Dal Khalsa spokesperson Kanwar Pal Singh and KAC Chairman Bhai Mokham Singh were among those taken into preventive custody by the Amritsar police on Wednesday morning.
The leaders of some Sikh outfits and hardline groups were taken into preventive custody early Wednesday in apprehension of breach of peace after a call that the newly-appointed jathedars would address the community from the Akal Takht.
Akal Takht head Gurbachan Singh's customary address on the occasion of Diwali drowned in the din on Wednesday amid slogan shouting by Sikh hardliners, even as parallely "appointed" jathedar of Akal Takht also managed to address the gathering but was arrested soon after.
Sikh organisations, including hardline groups, gathered to take part in 'Sarbat Khalsa', seeking to free Sikh institutions from political influence.
