BBC could launch legal battle over Sherlock Holmes after New York studio announces rival series for CBS

'We understand that CBS are doing their own version of an updated Sherlock Holmes', said executive producer at Hartswood Films Sue Vertue.

'We are very proud of our show and like any proud parent, will protect the interest and wellbeing of our offspring,' she told The Independent.

Ms Vertue said that CBS had made an offer to the BBC 'a while back' about filming a remake of the series but nothing had come of it.

She added that reassurances had been made about the network's integrity during talks and she hoped that their own version did not resemble the BBC's production.

The current series has been a huge hit in the States but is currently shown on PBS.
