Replying to a question, Deputy Election Commissioner Vinod Zutshi said following the report, the Commission referred the matter for investigation.
"We have nabbed one person who seems to be responsible" for it, he said, adding that "it seems to be prank, false".
The CPM on Thursday lodged a complaint with the EC about a suspect e-mail from an anonymous person who claimed to have the expertise to hack into EVMs.
The sender of the mail had opened an account in CPM's Bankura district committee secretary Amiya Patra's name and sent him a mail with the offer. Patra lodged an FIR with the Bankura police.
The party also sought urgent intervention of the EC to stop such instances.
