Yoga guru Baba Ramdev was detained and questioned at Heathrow Airport for over six hours by British customs officials.
There was lack of clarity over the reason for his detention at the airport.
According to one of the organisers of the function Ramdev is here to attend, he was questioned on books he was carrying which were in Hindi and Sanskrit. The officials detained Ramdev for over six hours before he was allowed to go.
However, a source said, Ramdev was questioned by customs officials as he came here on a visitor visa instead of a business visa.
