Angel Exford initially blamed the money mysteriously vanishing from her bank account on a fraudster.
It was only after some digging that she realised the culprit was her ex-boyfriend.
Michael Fehsenfeld had used over £1,200 of her money to book a trip to Pariswith a new partner and was met by police at the airport after Ms Exford tracked him down.
The pair dated for two months earlier this year.
During a dinner with friends he claimed he had lost his wallet, leading Ms Exford to give him access to her bank card.
“This is the night I believe he took my bank details,” the 29-year-old wrote on Twitter.
“This is the last night time I saw him in person”.
The couple broke up later that week and Mr Fehsenfeld then blocked his ex-girlfriend on social media.
