Two brothers wanted in connection with a deadly fire at their nightclub in the Indian state of Goa, which killed 25 people, have been detained in Thailand, India's ambassador to Thailand, Nagesh Singh, told the BBC.

Gaurav and Saurabh Luthra, who own Birch By Romeo Lane club, fled to Phuket, shortly after the incident last week.

"They will be sent back [to India]," Mr Singh said on Thursday, a day after a court in Delhi refused to grant them protection from arrest and the Goa government approached India's external affairs ministry to revoke their passports.

The brothers have not made any public statements but their lawyer told the court that they were being made victims of a "witch hunt".

The incident took in the early hours of Sunday, when a deadly blaze broke out at the club, located in a busy nightlife area of the popular tourist state.
