Three men have been arrested as part of the Financial Services Authority's (FSA's) and Metropolitan Police's ongoing fight against insider dealing and market abuse.
The men, all in their 30s, are being questioned after the police executed six search warrants in the City of London and Greater London areas on Wednesday. No charges have been made.
The regulator said the arrests were not linked to other insider dealing cases it is currently investigating. It has so far secured 21 convictions in relation to insider dealing and is in the process of prosecuting six others.
Insider dealing is a criminal offence that is punishable by a fine or up to seven years imprisonment.
