A Canterbury lifestyle block owner is facing animal welfare charges after allegedly beating four pigs with an iron bar.
The 49-year-old has already been charged with obstructing SPCA inspectors who visited his West Eyreton property on April 2 to investigate complaints of "serious physical abuse'" of his animals.
Police said he refused to comply with the inspectors' requests and allegedly abused and threatened them.
He then left the property with the pigs in a trailer and was stopped by police on the north bank of the Waimakariri River where he was allegedly found to have bullets and a knife.
He was arrested without incident and charged with wilfully hindering animal welfare inspector Geoff Sutton, refusing him access to inspect his animals and possessing .22 ammunition without lawful, proper, or sufficient purpose, and a knife without lawful authority or reasonable excuse and animal welfare offences.
