KOLKATA: Resurrecting the issue of cartoons lampooning her sent by email by a Jadavapur University professor, West Bengal chief minister Mamata Banerjee today claimed it actually contained a message threatening to assassinate her.She also alleged a conspiracy through Facebook Twitter and SMS and said "I am being shown in Facebook. Now, it is my turn. I will show you Facebook"."Mamata Banerjee is not a cartoon. A section of the media called it a cartoon. But they are wrong. It contained the word 'Vanish', which means a plan to assassinate and kill Mamata Banerjee," the chief minister told a party meeting in reference to the cartoon sent by Prof Ambikesh Mahapatra who was arrested and later released leading to a hue and cry."Why did the professor use someone else's email to send it? A professor is supposed to guide his students with good advice. If a rickshawalla commits a crime, it will be a criminal act. And if you commit a crime, you are professor. The law applies to all," she said.She also saw a political conspiracy on Facebook, Twitter and through SMS against her."There is a political conspiracy through Facebook, Twitter and SMS. I am being shown in Facebook. Now, it is my turn. I will show you Facebook," she warned. She also saw a larger conspiracy allegedly by CPM and Maoists."CPM always provides encouragement. Emails are being sent by ultra-Left backed organisations," she said.
