Robert and Vincent Tchenguiz arrested in Iceland probe
Property tycoons Robert and Vincent Tchenguiz are amongst seven men who have been arrested as part of an investigation into the collapse of Icelandic bank Kaupthing.
The Tchenguiz's offices in central London were raided on Wednesday morning.
Kaupthing, once Iceland's biggest bank, collapsed along with the bulk of Icelandic banks during the height of the banking crisis in 2008.
The brothers deny any wrongdoing.
