New Delhi/Kolkata, March 6 : Swinging into action against Trinamool Congress youth wing leader Vinay Mishra's brother, Vikas Mishra, in an alleged coal smuggling case, the central probe agency has issued a look out circular (LOC) notice. A senior CBI official in Delhi told IANS: "The CBI has issued a LOC against Vikas Mishra today." The action comes as West Bengal gets battle-ready for a crucial Assembly poll in March-April, with results expected on May 2. According to CBI officials, an LOC against Vinay was issued earlier as he has been absconding in the coal smuggling case. Now a LOC has also been issued against Vikas, the official said.

Following the questioning of Rujira and Gambhir, the CBI team also carried out searches in Kolkata on the premises of a businessman Randhir Kumar Barnwal on February 26 this year.

On February 19, the CBI had also carried out searches at 13 locations in four districts of West Bengal including the premises of coal mafia Jaidev Mondal.

Voting will take place on May 2. The ruling Trinamool Congress and the BJP are engaged in bitter war of words in the state. /IANS
