Yadav said the entire agitation seemed "a big conspiracy against citizens" of Haryana. He said the role of two Haryana ministers should be probed by the Central Bureau of Investigation (CBI).
He said an audio tape that had gone viral on social media purportedly had the political advisor to former chief minister Bhupinder Singh Hooda instigating a person named 'Captain' to unleash an aggressive agitation.
He said stringent action should be taken against the advisor if he was guilty.
Yadav said freedom fighter Rao Tula Ram's statue was demolished in Jhajjar and properties and businesses belonging to specific communities were targeted and torched.
He said the role of some senior IAS and IPS officers should be probed for not taking appropriate action against the mobs.
The Bharatiya Janata Party government had "totally failed" to control the agitators, causing huge losses to life and properties, Yadav said.
Gurgaon BJP legislator Umesh Aggarwal, in a separate statement, blamed Virender Singh, political advisor to former chief minister Hooda, for playing a role in the violence.
