Lancashire Road Police were tasked with trying to 'mooove' on a herd of cows after they descended on a service station last night.
The unruly herd 'hoofed' it to Rivington services on the M61 at around 1am where they caused 'udder chaos' on the petrol station concourse.
They were later seen surrounding a cash machine prompting police to wonder whether they were in fact "cash cows."
Officers attempted to reason with the beefy troublemakers but it went in one ear and out the 'udder'.
Police denied they were on a 'steak-out' and later contacted the farmer of a field to arrange the return of the bovine bandits.
A spokesman for the police said: "Patrols were asked to attend the services after around 20 cows escaped from a field.
"We established who the owner was and contacted the farmer who came out to the services.
"The cows were returned to their field by 3am. There was no disruption to motorway traffic."
No cows were harmed during the incident.
