The Enforcement Directorate (ED) has arrested a defence agent from Delhi in the Rs 3,600-crore VVIP choppers deal case, officials said Tuesday.
They said Sushen Mohan Gupta was arrested late Monday by agency sleuths under the Prevention of Money Laundering Act (PMLA).
Gupta, they said, has allegedly dealt in defence deals, including the AgustaWestland helicopters deal.
He will be produced before a special PMLA court here Tuesday.
Lawyer Gautam Khaitan and alleged British middleman Christian Michel were earlier arrested by the ED in the case.
