Mr Mallya's extradition is now before the British court where neither the CBI nor the ED is a direct party. Indian agencies primarily aid and assist British prosecutors with case material to counter the plea of absconders before the courts, an official explained.
The agencies' move to send a team to London is aimed at presenting a strong case for the extradition of the liquor baron before the court.
The 61-year-old was arrested by British authorities last month on India's extradition request in connection with loan default case of IDBI Bank, being investigated by the CBI. He was released on bail within hours by a London court which has fixed May 17 as the next date of hearing.
Vijay Mallya, whose now-defunct Kingfisher Airlines owes more than Rs 9,000 crore to various banks, had left India on March 2, 2016.
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 the right to appeal to higher courts against any decision all the way up to the Supreme Court.
Under the law, the British Secretary of State may only consider four issues when deciding whether to order a person's extradition - whether the person is at risk of the death penalty, whether special arrangements are in place, whether the person concerned has previously been extradited from another country to the UK and the consent of that country to his onward extradition is required and whether the person has previously been transferred to the UK by the International Criminal Court.
