Christian Michel, the alleged middleman in the AgustaWestland chopper deal, was extradited to India on Tuesday, 4 December.

Michel was brought to New Delhi aboard an Aviation Research Centre plane of the Research & Analysis Wing (R&AW) around 10.45 pm from Dubai. The operation was reportedly overseen by National Security Advisor Ajit Doval himself, and was coordinated by interim CBI Director M Nageswar Rao.

He had left Dubai on a special flight on Monday, 3 December, accompanied by a team of doctors and officials to ensure he stays fit.
