Chauhan was caught on camera leading a group of lawyers in mounting the assaults on two occasions -- February 15 and 17 -- at the Patiala House court complex, triggering widespread outrage and condemnation.
On Monday, a news channel had aired a sting operation in which the lawyer was seen boasting about beating JNUSU President Kanhaiya Kumar, charged with sedition, when he was brought to the court on February 17.
Police had issued multiple summons to Chauhan and some of his colleagues.
