The British government has reportedly certified his extradition request.
Sources said that he was likely to be produced before Westminster magistrate court in Tuesday.
He’s being wanted in India in connection with money laundering defaulting on hundreds of crores of banks loans.
India had revoked his passport and requested the British government to immediately deport the flamboyant businessman.
In February the Home Ministry had forwarded to the Ministry of External Affairs (MEA) a court-issued request to bring back embattled Mallya from the United Kingdom to India to face money laundering probe.
The arrest came weeks after Indian Finance Minister Arun Jaitley had indicated that Mallya’s extradition would feature in his talks during his visit to the UK.
India had given a formal extradition request for Mallya as per the Extradition Treaty between India and the UK through a note verbale on February 8.
While handing over the request, India had asserted that it has a “legitimate” case against Mallya and maintained that if an extradition request is honoured, it would show British “sensitivity towards our concerns”.
Last month, setting in motion the process of extradition of Mallya, the British government had certified India’s request and sent it to a district judge for further action.
The extradition process from the UK involves a number of steps including a decision by the judge whether to issue a warrant of arrest.
In case of a warrant, the person is arrested and brought before the court for preliminary hearing followed by an extradition hearing before a final decision is taken by the secretary of state.
The wanted person has a right to appeal to the higher courts against any decision all the way up to the supreme court.
Earlier in January this year, a CBI court had issued a non-bailable warrant against Mallya in the Rs 720-crore IDBI Bank loan default case.
Mallya is the owner of a Formula One team.
