Police issued a fresh notice to former West Bengal sports minister Aroop Biswas on Saturday, asking him to appear before investigators within 48 hours for questioning in a case related to the chaos at the Lionel Messi event at Salt Lake Stadium in December. Biswas had not complied with two notices sent by the Bidhannagar police earlier to appear before it for questioning in the case. He had sought time for appearance, citing personal reasons, sources said.
