It is alleged Cryan, a former employee at Tullett Prebon Group, conspired to defraud between 1 February 2009 and 3 December 2009.
He is the 13th person against whom the SFO has brought charges in respect of LIBOR. The SFO began its investigation, in conjunction with the Financial Conduct Authority and US agencies, in July 2012.
The first criminal conviction in the UK arising from the SFO’s LIBOR investigation was entered earlier this month, on 3 October 2014.
The investigation continues.
