The PIL was filed by advocate Bijayan Ghosh seeking a probe by CBI as he alleged that the West Bengal Police were acting in a partisan manner in the matter.
The advocate said that since the state government was not taking any action and was dealing with the issue in a "partisan" manner and if no action is taken, it will encourage other leaders to indulge in such activities.
In the petition, the advocate has made West Bengal government and CBI as respondents.
"If any CPI-M man is present here. Listen to me. If you ever touch any Trinamool Congress worker or their families at Choumaha, you have to pay for this. Don't try to act smart with me. I am smarter than you...
"... Earlier, you guys have bullied me on various occasions. If you insult the mothers and daughters of Trinamool workers. Then I won't spare you. I will let loose my boys in your homes and they will commit rape. I will teach each of you a lesson," the MP had warned.
