Metal thieves cause oil spill in Tewkesbury River Avon
A clean-up operation is taking place in the River Avon at Tewkesbury in Gloucestershire, after a break-in at a disused mill led to an oil spill.
Scrap metal raiders were said to have caused oil from damaged machinery at Healings Mill to leak into a drain.
The Environment Agency said steps were taken to minimise the risk of pollution and increase security on site.
Contractors have placed a boom in the river to contain the oil and the situation is being monitored.
Environment Agency spokesman Serena Balsdon said: "We would advise any owners of industrial property, operational or derelict, to review their pollution plans and security arrangements.
"The current high value of scrap encourages these types of incidents and it is often cheaper and always better for the environment to take preventive action, rather than clean up the aftermath."
ADM Milling, which owns the derelict building, has not yet been available for comment.
