Three British men who ran an international organised crime gang that conned UK investors out of £80m have been jailed for a total of 43 years by a US judge.
City of London police said the sentencing of Richard Pope, Paul Gunter and Simon Odoni was a "major milestone" in a seven year trans-Atlantic operation.
The investigation discovered at least 2,300 people - mostly retired professionals - lost money to the boiler room fraud. Individual losses ranged from a few hundred pounds to £1m.
City police said many victims had lost all their life savings.
One man committed suicide after losing more than £200,000, including £70,000 to this gang. His widow Andrea Goswami, from Yorkshire this year travelled to Florida to give evidence against the trio.
The fraud began in 2004 when Pope, 55, Gunter, 64, and Odoni ,56, and their co-conspirators acquired previously hijacked dormant publicly-traded companies in the US. They then sold UK investors worthless stock, the police said.
They operated a network of Spanish boiler rooms employing hundreds of people who targeted investors using high pressure and misleading sales techniques.
The men used the money to fund extravagant lifestyles which included a £350,000 private jet, 26 properties in the US and three in the Dominican Republic, and a number of high value cars and speed boats.
Detective inspector Kerrie Gower, who led the investigation for the City of London Police, said: “Pope, Gunter and Odoni are among the most arrogant, ruthless and destructive criminals the City of London Police has ever dealt with and deserve every day they will spend behind bars in the US."
Mrs Goswami added: "No prison sentence is long enough for these men after the damage they caused to the lives of my family and hundreds of others, especially as they continue to show no remorse for the dreams they destroyed and the fact that many of their victims have been left with nothing."
The three men, who were sentenced in Florida, will serve the following prison terms:
• Paul Gunter = 25 years
• Simon Odoni = 13 years and four months
• Richard Pope = 4 years and nine months
