Around 7.8 million UK adults used online dating sites in 2016, up from just 100,000 in 2000.
So what can you do to avoid being a victim of an online dating scam?
Jane advises meeting up with someone sooner rather than later - more often than not, scammers are based abroad and won’t be able to meet you.
Jane*, a middle-aged woman from Warwickshire, had a lucky escape a few years ago when she very nearly handed over a sizeable sum of money to an online scammer who did in fact claim to be an engineer.
Her interest was initially piqued when he seemed to have a similar background and heritage to her and they chatted for almost two months, often exchanging messages for at least two hours an evening.
Nancy*, a 47-year-old single mother from North Yorkshire was conned out of over £350,000 that way: “I wasn't comfortable, and then I got so far in I couldn't get myself out, and I didn't want to walk away having lost £50,000 or what-have-you, so you keep going in the hope that you're wrong and this person is genuine,” she explained to the BBC.
Nancy is now facing bankruptcy, and although her case is extreme, the average victim of online dating fraud loses £10,000 according to Action Fraud.
She is 5’6”, has never been married, and has long brown hair and blue eyes.
Photos used are often selfies of her wearing skimpy vest tops showing lots of cleavage.
One of the most common techniques is to build up trust with the person by messaging for weeks or even months before suddenly having an emergency - the fake person being mugged but their daughter needing urgent surgery, for example - and asking for money.
