The UK's financial watchdog formally is charging former Logica employee Majeet Singh Mohal with passing on inside information in 2012 and two other men - Reshim Birk and Surinder Pal Singh Sappal - with insider dealing.
None of the trio hailing from Southall has entered a formal plea after formally facing the charges at Westminster magistrates' court on Wednesday. Their solicitors were not available for comment.
The offence relates to trading in Logica shares in May and June 2012 when the company was taken over by the Canadian CGI Group. In March, former Logica financial planning manager Ryan Willmott was sentenced to 10 months imprisonment for insider dealing relating to the same takeover.
The Financial Services Authority, the organisation which the FCA replaced in 2013, prosecuted some people for the crime, but 27 individuals have been convicted for the crime under the new authority.
In a short statement the FCA said:
Mohal appeared in respect of two counts of insider dealing by disclosure of inside information, Birk in respect of one count of insider dealing by dealing in securities (shares and options) and Sappal in respect of one count of insider dealing by dealing in securities (shares).
