NSW Police have sought an apprehended violence order against William Tyrrell’s foster parents on behalf of a child linked to the missing boy.

Hundreds of officers have begun extensive searches on three locations in Kendall, where missing child William Tyrrell disappeared.

Channel 10 Investigative Journalist Lia Harris has had her podcast material into the missing boy subpoenaed by the Coroner’s Court.

It featured interviews with William’s foster mother and father.

“Obviously they were grieving parents who had lost their foster son,” Ms Harris told Ben Fordham.

“But they also, at the time, were extremely disappointed with the police investigation.”
