Maharashtra minister Nawab Malik on Tuesday accused NCB official Sameer Wankhede of illegal phone tapping and announced that he will hand over a letter on the official's "misdeeds" to the agency head. "Sameer Wankhede through two persons in Mumbai and Thane is illegally intercepting the mobile phones of some people," said Mr Malik, who has been targeting Mr Wankhede after his son-in-law's arrest.
