The Punjab Police on Thursday booked five people, including three based in the US, for sedition and promoting enmity following putting up of hoardings in Punjab seeking a referendum on separate Sikh State Khalistan.

The police filed a case against New York-based organization Sikhs For Justice (SFJ) legal advisor Gurpatwant Singh Pannun and SFJ activists Jagdeep Singh and Jagjeet Singh (all three based in New York), Gurpeet Singh of Mohali and Harpunit Singh of Jammu.
