The Congress on Tuesday reiterated its demand for a Central Bureau of Investigation (CBI) probe into the attack on the house of Uttar Pradesh party chief Rita Bahuguna Joshi, who was arrested July 15 for making derogatory remarks against Chief Minister Mayawati.

"If the probe is not ordered we will launch a statewide protest. We want to expose the Mayawati government on the issue of the state sponsored act of violence, corruption and misgovernance," Akhilesh Pratap Singh, Congress spokesperson, said.
