Four people have been left nursing serious wounds after they were attacked and mauled by seven pit bulls in Delareyville in the North West.

The latest victim was admitted at Gelukspan Hospital after he was attacked on Friday by the dogs that nearly bit off both his lips.

The incident was the fourth such attack by the dogs in four months, said angry residents who want them leashed.

Two owners of the dogs were arrested and released on R2,000 bail each.

They have not been identified. The pair will appear again at the Delareyville magistrate's court on April 5.

North West police spokesperson Lt-Col Amanda Funani said the dog owner and her husband were charged in terms of the Animal Matters Amendment Act, which provides for direction in respect of injuries caused by animals.

Residents say they have been living in fear of the vicious pit bulls that are kept at a house near a busy street.
