Kingsbridge and the companies associated with it provided specialist financial advice to high net worth clients between 1992 and 2010, when the company ceased trading.
The police believe there could be hundreds of people affected by this alleged activity, which resulted in significant financial losses, who may be victims of fraud.
In 2015, International Adviser reported that as many as 100 top footballers had collectively lost £100m ($139m, €115m) by investing in film and property ventures through Kingsbridge.
On Thursday, detectives from the City of London Police’s Fraud Squad arrested a 60-year-old man from Blackburn and two men aged 61 and 38 from Nottinghamshire on suspicion of conspiracy to defraud in connection with this investigation.
The three men have since been released under investigation.
Come forward and be heard
Anyone who was a client of Kingsbridge or its associated companies and believes they may have been defrauded, has been urged to come forward.
Those with information concerning the activities of Kingsbridge have also been encouraged to contact the police of Action Fraud.
Detective superintendent Perry Stokes, who is the senior investigating officer for the case, said: “We are encouraging anyone who believes they are a victim or anyone who has information about Kingsbridge Asset Management or companies associated with it, to come forward.
“We are aware that there may be many people impacted by the activities of this company and it is vital that those affected come forward so their voices are heard and we are able to support them and provide the advice that they may need.”
