Detectives have been left stumped after honest villagers repeatedly handed in cash bundles of £2,000 found on their streets.
Villagers of Blackhall Colliery in County Durham have been praised by the police for handing in 12 cash bundles left in the street over five years.
The unusual discoveries have been made since 2014, including four this year, with the latest find taking place on Monday morning.
The money is almost always comprised of £2,000, always found in a bundle of £20 notes and always left in plain sight, although in different locations throughout the village.
The motive for leaving the money is unknown, with some speculation that it could be a generous Good Samaritan.
- What would you do if you found the cash?
Detective Constable John Forster, of Peterlee CID, said the team had interviewed numerous people and organisations in the village as well as carrying out checks with the local bank and post office and even tested for fingerprints, but the circumstances surrounding the bundles of money remain a mystery.
If you have any information call 101 and ask to speak to DC Forster of Durham Constabulary.
