A 44-year-old man employed at Legal & General Investment Management, one of the UK’s largest investment firms, has been arrested by the Financial Services Authority (FSA) in connection with a two-year probe into insider trading.
It is the regulator’s ninth arrest in two years in connection with its largest operation against alleged insider trading, the Financial Times reports.
The man is believed to have been a trader who worked at LGIM for several years.
This latest arrest, of a City individual, is part of the FSA’s investigation into deals spanning three years to 2010 in shares in companies including Paragon, Barclays, Scottish & Newcastle, National Express, Petrofac, Wolseley and Collins Stewart.
In March 2010, more than 140 officers carried out dawn raids on 16 addresses across London and the south-east seizing documents and computers.
Seven men were arrested: Julian Rifat, a trader at hedge fund Moore Capital; Martyn Dodgson, a corporate adviser at Deutsche Bank; Graeme Shelley, a broker at Novum Securities; Clive Roberts, trader at Exane BNP Paribas; Iraj Parvizi, an Iranian-born businessman and investor in small-cap stocks; Ben Anderson, a private stock broker; and Andrew Hind, a director of Deskspace Offices. The FSA then arrested an eighth man in April 2011.
The regulator is investigating spread bets on shares of at least 500 companies between October 2007 and January 2010 that allegedly made profits of at least £21.6m, the FT reports.
All individuals arrested were interviewed under caution and then released on bail. They have not been charged with any offence, and are believed to deny any wrongdoing.
The FSA, which is in the process of being split into two agencies by the government, has stepped up efforts to clamp down on insider trading in recent years. It has so far secured 11 convictions and is in the process of prosecuting 16 other individuals for alleged insider dealing, which is a crime with a maximum sentence of seven years.
