Thapar, 60, was arrested under the Prevention of Money Laundering Act (PMLA) on Tuesday night after the agency carried out raids against him and his linked businesses in Delhi and Mumbai, they said. He is expected to be produced before a court on Wednesday where the ED will seek his custody, they added. The ED has been probing an alleged transaction between his company Avantha Realty, Yes Bank co-founder Rana Kapoor and his wife, who are already being investigated under the PMLA by the agency.
