A teenager has been charged in connection with the theft of radioactive material on Teesside.
Roads were sealed off after iodine, in a lead container, went missing from a delivery van in Port Clarence, near Hartlepool on Friday.
The container was later found on an allotment, and police said it appeared to be intact.
Cleveland Police said a 17-year-local male had been charged with handling stolen goods and bailed.
The substance, which is safe as long as it is contained, was destined for Middlesbrough's James Cook University Hospital.
Detectives say they are "actively searching" for others suspected to be involved in the incident.
