Sandeshkhali accused Shajahan Sheikh was handed over to the CBI by the West Bengal Police on March 6 after an order by the Calcutta High Court.
The High Court had asked the Crime Investigation Department (CID) to hand over the suspended TMC leader on March 5, but the cops had refused after the Mamata Banerjee government challenged the order in the Supreme Court.
Shahjahan was held on February 29 after absconding for two months since his supporters attacked a team of Enforcement Directorate (ED) officials who had gone to Sandeshkhali for an investigation in connection with a ration scam probe on January 5.
On February 18, a group of women staged protests in Sandeshkhali accusing Shahjahan and his supporters of sexual assault.
