"I was implicated in false cases and was treated like a terrorist in the jail. Torching of my house (in the state capital) was also state-sponsored," she told mediapersons in Lucknow.
Joshi said she will not settle to anything less than a Central Bureau of Investigation probe into the arson incident at her house on July 15, adding without such an inquiry, "real culprits cannot be nailed."
The state Congress chief had moved a writ petition in the Allahabad High Court seeking a CBI inquiry into the attack on her house. It will come up for hearing on Friday.
The Congress would launch state-wide protests, including fill the jail stir, from August 1 if the demand for a CBI probe was not met by then, the UPCC chief said.
"Law and order has ceased to exist in UP. We will not allow the anarchy to continue in the state any more," she said.
Asked to comment on the state DGP distributing cheques to rape victims and others who had been wronged, Joshi said this was improper and unfair.
Going on helicopters, which entails a huge expenditure, to distribute meagre financial relief to the victims was not proper, she said.
On ruling Bahujan Samaj Party's allegations that the Congress was plotting to kill party supremo Mayawati, Joshi said she had been the Chief Minister four times and if she feared for her own life, what would happen to 18 crore people in UP.
"I take pity on her," she said. On Thursday, BSP general secretary Satish Chandra Mishra alleged the Congress-led United Progressive Alliance government at the Centre wanted to eliminate Mayawati by withdrawing her National Security Guard security cover.
