Trouble started after thousands of people travelling in around 60 buses tried to enter Delhi via the Ghazipur border with Uttar Pradesh in the afternoon, police sources said.
As police foiled their attempt, the protestors resorted to arson by burning a mini-truck and two cars, they said, adding two fire tenders were pressed into service to douse the flames.
The people from UP were keen to reach Jor Bagh to join a protest against alleged attempt to grab wakf land by a Congress leader belonging to the minority community.
Traffic problems were also encountered in Jor Bagh and Lodhi Road and adjoining areas like Aurobindo Chowk, Safdarjung Madrasa, Tughlak Marg. Two Metro stations -- Jor Bagh and INA -- were shut down to prevent protestors from reaching the disputed site.

"On advice of Delhi Police, due to security reasons, INA and Jor Bagh Metro stations were closed for passenger service at 3:20 PM and later re-opened at 6:23 PM," DMRC spokesman said.
