A PCSO stole £15,000 from passengers at Gatwick Airport.
Alexis Scott, 39, approached passengers at the gate as they were about to board their flights and asked how much cash they were carrying.
In some cases, she told passengers they were carrying too much and confiscated the 'excess' telling them they could reclaim it when they returned.
She would then put the money under her hat and remove it after returning to the police station.
Her crimes were discovered when passengers returning from their holidays began asking where they could claim back their money.
Following a complex investigation and a three week trial, Scott, from Plumstead, London, was found guilty of six offences of theft and one of misconduct in public office. She was found not guilty of one count of theft. She was remanded in custody for sentencing on a date to be confirmed.
Deputy Chief Constable Olivia Pinkney said: "Sussex Police expects the highest personal and professional standards of everyone who works for us.
"Scott fell woefully short of those standards, abusing the trust that we had placed in her, but more importantly, the trust of the public and in particular, the victims of her crimes.
"Passengers and other users of Gatwick Airport rightly expect that those who wear the uniform of Sussex Police do so with integrity and honesty.
"Scott failed in this simple requirement and has been duly punished, but this mustn't be allowed to reflect upon the professionalism, honesty and integrity of other employees of Sussex Police who work tirelessly and selflessly around the clock.
"This was a complex and detailed investigation of an audacious act, but any such act will not be tolerated and we acted swiftly and decisively as soon as it came to light."
A Sussex Police internal disciplinary investigation took place last year and as a result Scott attended a gross misconduct hearing on July 16, 2013, and was dismissed immediately.
