A gang of robbers raided Upper Norwood library last week - but luckily cops were on hand to bring them to book.
A tiny team of child crooks stocked up the Westow Hill library's crime section during a day of fancy-dress fun on Thursday.
They soon found themselves at Gipsy Hill police station, but thankfully were let of with a look at vintage police cars parked outside instead of a night in the cells.
Officers were also on hand to offer eggs-pert advice to crack an Easter-themed mystery.
