An American student has returned her room key to the University of Cambridge, 40 years after accidentally taking it back to the USA with her.
Carla Risoldi had been a summer school student at Gonville & Caius College for six weeks in 1985, but in her haste to make her flight back home, she forgot to return her key.
The error would usually incur an initial £10 fine with interest of £10 per week added on top, the college said.
Four decades later than planned, she returned it during a trip to the UK. Ms Risoldi said she was relieved to know the college decided to waive the £20,000 fine.
