Delhi Police have dismantled multiple illegal LPG storage and refilling units across the city, seizing a large number of cylinders and apprehending several individuals involved in the illicit operations.
Local residents claimed the killing was not a fallout of Saxena being in an interfaith relationship.
Police said some "unsubstantiated reports" of tension in southeast and west districts were circulated on social media.
The prohibitory orders would be in force till September 8, a senior police officer told PTI.
Four accused, including a juvenile, were sent to judicial custody on Saturday in connection with the case.
