The Delhi Police is likely to file a reply in the Supreme Court on its crackdown yoga guru Baba Ramdev's supporters in Ramlila Maidan on the night of June 4.
The force had to submit its reply before June 20, but may have to do so on Friday as June 18 and 19 are holidays.
The Supreme Court on June 6 had issued notices to union home secretary GK Pillai and Delhi Police chief BK Gupta asking them what were the circumstances under which yoga guru Baba Ramdev and his supporters were forcibly evicted.
An apex court bench of justice BS Chauhan and justice Swatantar Kumar took suo motu cognizance of the police action against yoga guru Baba Ramdev, referring to media reports.
Delhi Police has scanned CCTV footage of the Ramlila grounds, where Ramdev was on an anti-corruption fast along with his supporters, as well as video footage provided by TV channels.
"Evidence suggests that most people were injured due to stampede, not because of lathicharge. But the timing of the crackdown is odd and the Delhi Police is finding it difficult to justifying that," said a senior police officer on condition of anonymity.
"Choosing 1am to disperse the sleeping crowd was absurd," the officer said.
Medical reports from various hospitals show that 30 of 39 supporters admitted were injured due to stampede, police said.
Ramdev and thousands of his supporters who were at Delhi's Ramlila ground were forcibly removed by police on June 4.
