Actor Robin Williams has been found dead at his home in California, police have said.

Police believe Williams, 63, known for films such as Good Morning Vietnam and Mrs Doubtfire, took his own life.

In a statement, Marin County Sheriff’s Office said: “At this time, the Sheriff’s Office Coroner Division suspects the death to be a suicide due to asphyxia, but a comprehensive investigation must be completed before a final determination is made.”

It added that an investigation into the “cause, manner, and circumstances of the death is currently under way”.

A forensic examination is expected to take place today, with toxicology tests to take place later.
