Thousands of pounds found in Spalding waterway
About £60,000 has been found floating in a Lincolnshire waterway.
A dog walker spotted the banknotes in the South Drove Drain in Spalding.
Officers said a large number of the notes were damaged but "a good quantity" appeared to be in reasonable condition.
The county force is considering carrying out a detailed forensic examination of the money in an attempt to trace where it came from.
Magistrates have granted a seizure order to allow police time to investigate the find.
Det Con Steve Hull, of Spalding CID, said: "It isn't every day that an amount of money like this is found.
"Somebody must have information that will help trace the lawful owner."
The money will remain with police until the investigation is complete.
If the money cannot be reunited with a legitimate owner then it will become the subject of a further court forfeiture order.
The force said anyone hoping to claim the money will need to provide proof of ownership.
