Cattle rustlers have stolen four bulls from a farm near Lancaster.
Police said the theft took place overnight between Tuesday and Wednesday last week at Bull Bank Farm in Wennington.
The bulls, which were taken from a field, had been tagged in both ears with DEFRA registration chips. The numbers are 182413500459, 103409300635, 182075400069 and 125659500897.
Police are now appealing for anybody with any information about the theft to come forward.
PC Ben Hanley said: “I would like to appeal to local markets which sell livestock to check the registration chips of cattle being brought in to see if they match any of the stolen bulls.
“I would also urge people buying livestock to be vigilant and check the tags. If anybody has any information at all about the theft then I would urge them to contact police.”
Anybody with any information is asked to contact police on 08451 25 35 45 or call Crimestoppers on 0800 555 111.
