Three British men have been arrested as part of an investigation into the rigging of interest rates, the UK Serious Fraud Office said on Tuesday.

The SFO said the men, aged 33, 41 and 47, are being questioned at a London police station, and that it and the City of London Police executed search warrants on a home in Surrey and two homes in Essex. A spokesman for the SFO said he couldn't give any further details.
