Violence and arson spilled over to the national capital from neighbouring Haryana after self-styled godman Guru Ram Rahim's conviction in a rape case, forcing the Delhi police to clamp down prohibitory orders.
The prohibitory orders would be in force till September 8, a senior police officer told PTI.
"As a preventive measure, we have enforced Section 144 of the CrPC in Delhi in 11 police districts," said SBK Singh, special commissioner of police (Law and Order, North).
The national capital has 13 police districts. North and central districts will not fall under the ambit of the orders, since no incidents were reported from there, the officer said.
Section 144 of the Criminal Procedure Code (CrPC) of 1973 empowers an executive magistrate to prohibit an assembly of more than four people in an area.
In a tweet, he also assured Delhiites about adequate security arrangements being in place.
"All SHOs, ACsP, DCsP and Jt CPs are patrolling the area to prevent any kind incident which may arise due to Ram Rahim followers in Delhi (sic)," he posted on Twitter.
Fire department officials said shey received calls about fires from Khyala, Badarpur, Manglapuri, near Babu Jagjivan Ram Hospital, Mandoli, Mehrauli, Samaypur Badli, Anand Vihar railway station and other parts of the city.
Lieutenant Governor Anil Baijal directed the city police commissioner to take effective measures to ensure peace. Chief Minister Arvind Kejriwal issued an appeal for peace.
Incidents of arson targeting buses were reported from several parts of the city.
Delhi police’s Public Relations Officer Madhur Verma said five "miscreants" were arrested for allegedly attempting to set buses ablaze in Badarpur and Khyala areas.
He said cases have been registered and it was suspected that these people were followers of Dera Sacha Sauda chief. The police have procured CCTV footages for further probe.
Delhi police officers are on a night vigil, he said.
