The founder of London-based gaming website Betonsports has been arrested and sent to the US to answer criminal charges, US officials have said.

Gary Stephen Kaplan was arrested in the Dominican Republic last week. In June last year, Kaplan was one of 11 people indicted on charges of racketeering, fraud, tax evasion and conspiracy.

Betonsports closed down its US operations in August 2006. The US had been the group’s biggest market, delivering around 95 per cent of its profits.

Following his arrest at a hotel in Santo Domingo, Kaplan was sent by Dominican authorities to Puerto Rico for an initial appearance before a US magistrate.
