After Gujarat Chief Minister Narendra Modi accused the Congress-led UPA government of sending the Central Bureau of Investigation (CBI) after him, the Uttar Pradesh Chief Minister Mayawati has now said that Centre was misusing the agency against her in the disproportionate assets case.

Mayawati questioned how CBI takes cognisance of theIncome tax report in case of leaders like Samajwadi Party's Mulayam Singh Yadav and RJD chief Lalu Prasad Yadav but when it comes to her it was trying to "frame" her in the DA case, BSP sources said.

These comments come in the backdrop of CBI telling the Supreme Court that it had gathered "credible evidence" to prosecute Mayawati in the DA case.

Besides this, the Chief Minister has already set her eyes on the upcoming assembly elections in Uttar Pradesh in 2012.

She has cautioned BSP workers against any design or conspiracy by political opponents through several tactics like sting operations ahead of the polls.

Mayawati has also asked them to apprise the general public against any such move, sources said.
