Three arrested in SFO Libor-rigging investigation The unnamed men, all British nationals, aged 33, 41 and 47, were taken into police custody at addresses in Surrey and Essex as part of a Serious Fraud Office investigation into interest rate manipulation. In a statement the SFO said: "Three men, aged 33, 41 and 47, have been arrested and taken to a London police station for interview in connection with the investigation into the manipulation of LIBOR. The men are all British nationals currently living in the United Kingdom. Barclays is the only bank to have been fined over attempts to manipulate Libor. In June, the bank paid £290m to settle investigations by the US and British authorities over its attempts to manipulate key global borrowing rates. Royal Bank of Scotland is expected to announce its own settlement over Libor-rigging by February, while Swiss bank UBS is also understood to be close to reaching a deal over the allegations. Last month, it was reported that the SFO was close to making arrests and was poised to arrest former traders and rate setters who had worked at all three of the banks.
