Linda Blair's animal shelter is under investigation by Los Angeles authorities after one of her rescued dogs escaped and attacked a neighbour's pet pig.
The Exorcist star runs the WorldHeart Foundation rescue centre in L.A., where she keeps up to 50 abandoned dogs at a time.
On Sunday (17Jan10), one of the canines under Blair's care managed to break free from its kennel and maul Gerty the pig, which was housed at a nearby ranch.
The pig's owner shot the pooch, insisting it had the pig in a "death grip". Despite being "devastated" by the incident, Blair offered to pay the pig's medical bills.
But officials at the L.A. County Animal Care and Control department have now launched an investigation into Blair's kennels to see how the dog escaped, according to TMZ.com.
