"The prohibitory order relaxation has been effective from 6 a.m. and will go up to 5 p.m. (Thursday)," Joint Commissioner of Police Sanjay Beniwal told IANS.
Two groups of Hindus and Muslims clashed on Diwali Oct 23 after which the authorities imposed prohibitory orders banning gatherings and movements of people.
Police Wednesday gave a six-hour relaxation in view of the Chhath Puja.
Besides, police decided to organise a community meeting Thursday.
"We will hold a meeting with both the groups and they would also sing national anthem, so that we can inculcate a sense of harmony and bring peace in the area," said Beniwal.
So far, 68 people have been arrested for the clashes.
Trilokpuri, divided into 36 blocks, is being manned by over 1,000 security personnel from Delhi Police, Rapid Action Force and Central Reserve Police Force along with over 30 police vans, water cannons and riot control vehicles.
