LONDON - A British businessman has taken the unusual step of seeking a private prosecution against a computer expert wanted in the United States on terrorism charges, his law firm said on Thursday.

Karl Watkin, who made a fortune from bio-fuel and internet companies, said it was a "disgrace" that Babar Ahmad had not been brought to trial in his home country eight years after he was arrested.

Ahmad has been held in a British jail while his lawyers have been fighting his extradition. The European Court of Human Rights in Strasbourg is currently reviewing whether sending Ahmad to the United States is lawful.
