The Uttarakhand administration imposed Section 144 CrPC that prohibits assembly of more than four persons in Roorkee where a Dharam Sansad was scheduled on Wednesday.
The police have detained around 10 persons associated with the event.
A day ago, the Supreme Court directed the Uttarakhand Chief Secretary to place on record that no untoward statement would be made at the event at Dada Jalalpur village and warned that it would hold top officials responsible in case of any hate speech is made.
