Radical Sikh organisations, including Damdami Taksal, have called the bandh to protest the killing of Darshan Singh in alleged police firing in Ludhiana on Saturday.

The police allegedly opened fire on a group of persons owing allegiance to radical Sikh outfits protesting holding of a religious congregation by Divya Jyoti Jagran Sansthan sect head Ashutosh Maharaj.
