Police said in a statement that "initial indications" suggested a week-old-boy in Shropshire died as a result of being bitten by the dog.
Our investigation is ongoing but it appears that the baby died as a result of a dog bite. The dog in question was a family pet - a Jack Russell - and this animal has been put down.
A post-mortem will be taking place to establish the exact cause of this baby's death but at this stage it does appear to be a tragic accident.
