About 300 people were taken to hospital. Police said at least half of the injured were security personnel and also arrested about 70 protesters - most of them have since been released on bail.
After ignoring the protesters for nearly five weeks, Modi finally broke his silence on Thursday to say they had "decided to set up fast-track courts to ensure swift and stringent punishment for those involved in paper leaks".
And later that night, Modi posted a video message saying that a tough new law on examination paper leaks was being prepared. He said he had received a draft of the law, which they wanted to introduce soon in parliament.
Thousands of posts mocking Modi have flooded social media. The prime minister's videos, intended to quell anger, have been turned into jokes and memes.
Following Pradhan's resignation, the CJP founder Dipke said in a statement on X that the fight was not over yet.
He said they would continue to fight for the families of students who died by suicide after a key medical exam was cancelled to ensure they received compensation.
He also renewed his calls for action against police officers he accused of using excessive force against protesters on 20 July on CJP supporters who tried to march to Parliament.
"Remember, do not mess with [the] cockroach," he added.
