Interpol on Monday issued an arrest warrant for India's billionaire diamond merchant Nirav Modi, tightening the noose on one of the main suspects in a $1.8-billion fraud at a major state-run bank.
Modi, thought to be in London, is a jeweller to the stars whose celebrity clients have included Naomi Watts and Kate Winslet. His eponymous high-end brand has stores in several of the world's major cities.
India last month requested Interpol to issue a so-called red corner notice to help trace Modi after the fugitive diamond merchant was last spotted in Britain.
A red corner notice seeks the arrest or provisional arrest of wanted persons with a view to extradition.
Indian authorities have charged Modi with money laundering and several Indian courts have issued arrest warrants over his failure to appear before them since he fled the country in February.
