A baby is recovering after suffering fractures and bruising consistent with being shaken and bitten by an adult, police say.
A police strike force has been set up to investigate the suspected assault of the Lake Macquarie boy, who was just nine weeks old when he was admitted to a Newcastle hospital on September 7.
"While the exact cause of the injuries are unknown at this time, medical experts have told police that the fractures are consistent with the baby being shaken, and the bruising is consistent with the child being bitten by an adult," police said in a statement.
Newcastle-based detectives from the child abuse squad have formed Strike Force Glendevie and are appealing for information about the suspected assault.
Now aged 16 weeks, the child is reportedly recovering well and in the care of the Department of Family and Community Services.
