The restrictions under Section 144 of the IPC prohibit mass gathering, a police officer said.
More than two companies of the Delhi Police have been stationed in and outside the jail premises. Water canons, barricades and other security measures have been put in place.
"Additional police force has been stationed outside the premises of Tihar Jail because we apprehend that AAP workers will again protest here today (Thursday)," Deputy Commissioner of Police Ranvir Singh told IANS.
A number of AAP workers, including senior party leader Yogendra Yadav and Manish Sisodia, were detained by the police following the protests.
