Police confirm the “very unusual find” of banknotes in a refuse sack and are investigating whether criminals are involved.
A bin bag stuffed with thousands of pounds of cash has been left on the doorstep of a former vicarage.
North Yorkshire Police will not reveal the exact amount of money in the sack that was handed in to officers on Tuesday.
A spokesman said Tuesday was bin collection day in that part of the city.
Officers are appealing for the public’s help to work out what has happened.
Detective Inspector Andrea Kell, of York CID, said: “This is a very unusual find which remains unexplained and we would like to find out where the money came from and rule out any criminal connection.”
Det Insp Kell said the bag was found outside the former vicarage at 10am and she believes it was left at some point during that morning.
