British authorities arrested a ninth person in an insider-trading case whose first collars came almost two years ago.
A Legal & General Investment Management employee was arrested this week and questioned at a London police station before being released on bail. The arrest follows seven in early 2010—including employees of hedge funds Moore Capital Management and Aria Capital—and another in April.
The Moore employee arrested was execution trader Julian Rifat.
The Financial Services Authority and U.K. Serious Organized Crime Agency are investigating possible front-running by the suspects.
In addition to arresting the 44-year-old L&G employee, who was not identified, police searched an office and home in London and another home in Kent.
