Sisodia's accusations came after Kanhaiya told a Supreme Court-appointed lawyers' probe panel that he was beaten up by men in lawyers' robes before the police, video of which was aired on TV channels today.
"Delhi Police was only partner in the whole incident that day and did nothing to prevent the attack at the Pataila House court complex...Police orchestrated the incident," the deputy chief minister told reporters here.
"Despite deployment of 800 cops at the court complex, how could such an incident take place? In the video, senior police officers of New Delhi Range are being seen but they are doing nothing to prevent this incident," Sisiodia alleged.
"What action has Bassi taken against these police officers?...Action should be taken against Bassi before his retirement," he said.
Bassi will be retiring on February 29.
Kumar has told the apex court-appointed panel that he was beaten up, pushed to the ground and injured by men in lawyers' robes in the presence of the police when he was brought to the Patiala House court premises on February 17.
