On Thursday, Surrey Police arrested two men and one woman on suspicion of fraud by false representation and money laundering.
In total the operation has seen 10 people arrested for the scam.
Romance fraud is when a person uses a fake profile online to form a relationship with someone.
The fraudster aims to gain the victims trust over a long amount of time, causing the victim to gain feelings for them, before taking their money or personal information.
Investigating officer DC Mason said, “Romance fraud is a particularly cunning, cruel and highly manipulative crime.
“The impact this leaves on victims can be devastating.
“I hope this action today encourages victims of online romance fraud to come forward and report it so those responsible can be brought to justice.”
Romance fraud increased by a third in 2020 compared to 2019, with the pandemic being a factor for dating more online.
Already this year Surrey Police and Sussex Police have seen 186 reports of romance fraud.
