The Supreme Court on Monday 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.
A notice has also been issued to Delhi chief secretary PK Tripathi which has to be answered in two weeks.
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.
Ramdev and thousands of his supporters who were at Delhi's Ramlila ground were forcibly removed by police after Saturday midnight.
Ramdev was airlifted to Dehradun from where he was taken to his ashram in Haridwar on Sunday morning.
The court said the matter will be listed in the second week of July for hearing.
