Lucknow: Charging the Uttar Pradesh government with 'shielding' the culprits in the Meerut lecturer Kavita Rani's murder, the BJP and CPI today demanded a CBI inquiry into it.

In a statement issued here today state BJP spokesman H N Dixit alleged that the police has embarked upon a massive cover up to "shield" the ministers allegedly involved in the case.

Only a CBI inquiry can unravel the mystery, Dixit said.

The CPI also demanded a CBI probe into the matter and claimed that the victim's family also desired the same.

Senior CPI leader Ashok Mishra has written a letter to the Chief Minister seeking stern action against the culprits.

"The ministers' involvement has been proved by the letters recovered from her residence," Mishra alleged.
