A 21-year-old has been arrested and interviewed as part of a Financial Conduct Authority (FCA) investigation into boiler room fraud.
The person was arrested by Kent police on Wednesday morning after the force, together with the FCA and National Crime Agency, executed search warrants at addresses in London and Kent.
The person has not yet been charged and the regulator has released no further information at this point.
The arrest follows a string of FCA crackdowns on investment fraud in recent months.
In January the regulator and City of London Police arrested two men and one woman in connection with a fresh boiler room investigation in the Kent, Essex, and Bedfordshire areas.
Earlier in the month it warned of another boiler room scam operating under the same name as authorised firm LBV Asset Management.
Last November FCA shut down suspected boiler room scam First Capital Wealth by placing an unlimited worldwide asset freezing order on the company while banning it from selling selling investments regulated by the FCA.
The FCA warned that boiler room operations usually use "high-pressure selling techniques to persuade consumers to buy shares that are often worth very little or nothing at all".
Because the people selling shares through boiler rooms do not have permission from the FCA to do so, boiler room scams are unauthorised business.
Carrying out unauthorised business is an offence punishable by terms of up to two years imprisonment or a fine, or both, and making misleading statements is punishable by up to seven years imprisonment or a fine or both, the FCA added.
