Two sheep have been seriously injured during a dog attack on a farm in Crick.
The incident, which happened sometime between 6.15pm and 6.45pm on Saturday, October 25, saw one of the animals have its ears bitten off by the dogs.
Another sheep was also seriously injured in the attack, which is believed to have been carried out by two lurcher-type dogs.
It is believed that two men took the dogs into the field and officers investigating the attack are keen to trace them.
It is an offence for a dog to worry livestock and both the owner of a dog and the person in charge of it if they are not the owner, can be prosecuted.
Anyone with any information about this incident, or who has been a victim of livestock worrying, can call Northamptonshire Police on 101 or Crimestoppers anonymously on 0800 555111.
