The UK court, hearing extradition case against embattled businessman Vijay Mallya , has ordered Indian authorities to submit a video of Mumbai jail cell where the Indian authorities plans to keep Mallya after extradition. The court has given Indian authorities three weeks of time to submit the videos to see the windows of the cell and find out whether the cell receives appropriate natural lights.Adjourning the closing argument in the high-profile case to September 12, Judge Emma Arbuthnot asked the Indian authorities to submit a "step by step video" of Barrack 12 for "the avoidance of doubt" over the availability of natural light in the cell where the 62-year-old businessman is expected to be kept after the extradition. Indian authorities had provided photos of the cell but the court find photos inconclusive."I would like a video of Barrack 12, to see where the windows are... shot maybe at mid-day with no artificial lighting," Judge Emma Arbuthnot ordered.Vijay Mallya's defence lawyers had challenged the extradition on four grounds including claims that he had no "fraudulent" intentions and that he is unlikely to get a fair trial in India under inhumane conditions in prison.Assuring proper facilities in the jail, Indian authorities told the UK court the Mumbai Arthur Road jail has proper "private" and adequate washing and toilet facilities that are regularly cleaned and have western-style functioning flow of water and clean mattress and bedding.But Mallya's defence team focused its objections on the lack of natural light available in Barrack 12 as it claimed that the "government of India assurance cannot be relied upon"."The photos show natural light flooding into the cell. But our (expert's) assessment is that... it is very difficult to work out where the light was coming from. Whatever the light is, is not natural light," said the defence lawyer.In the ongoing extradition proceedings, if the judge rules in favour of the Indian government, the UK home secretary will have two months to sign Mallya's extradition order. However, both sides will have the chance to appeal in higher courts in the UK against the Magistrates' Court verdict.UK-based Sanjeev Kumar Chawla, wanted in India as a key accused in the cricket match-fixing scandal involving former South African captain Hanse Cronje in 2000, had been discharged by a UK court in October last year on human rights grounds over severe conditions in Delhi's Tihar Jail, where the accused was to be held on being extradited.Earlier in the day, Vijay Mallya had expressed intentions to settle dues with Indian banks.(inputs from PTI)
