A week-old baby who was killed after being bitten by a dog in Telford died from a "significant" head injury, police have said.
Officers investigating the death of Harry Harper confirmed a post-mortem examination had been completed.
Harry was pronounced dead after being taken to Telford's Princess Royal Hospital from a semi-detached house in Telford, on Tuesday morning.
Police have said that "initial indications" suggest the baby died as a result of being bitten by the family's pet Jack Russell, which has since been put down.
A post-mortem concluded the cause of death was a significant head injury, West Mercia Police said.
Further detailed tests are still to be carried out and therefore no further information can be released, the force added.
