The arrival comes one year after Cameron was released from prison after serving seven years for drug possession.

He received a five-year sentence for possession of heroin and selling methamphetamine.

His sentence was extended when he admitted to smuggling drugs into prison. 

The star - who appeared in 2003's It Runs In The Family with his dad Michael as well as grandfather Kirk Douglas, 101 - has been sober ever since.

He added: 'I feel in the deepest recesses of my heart that there is a beautiful purpose hidden along this painful journey.'

In 2013 Michael - who is best known for TV's The Streets Of San Francisco and the movie Basic Instinct - told Vanity Fair he was 'very disappointed in the system' when his son was not released from prison.

'My son is in federal prison,' he told reporters. 'He’s been a drug addict for a large part of his life. Part of the punishments—if you happen to have a slip, and this is for a prisoner who is non-violent, as about a half-million of our drug-addicted prisoners are—he’s spent almost two years in solitary confinement. Right now I’ve been told that I can’t see him for two years. It’s been over a year now. And I’m questioning the system.'

He went on: 'Obviously at first, I was certainly disappointed in my son. But I’ve reached a point now where I’m very disappointed with the system. And as you can see from what Attorney General Eric Holder has been doing regarding our prison system, I think things are going to be revived, regarding nonviolent drug addicts. My last comment on that is the United States represents 5 percent of the world’s population and we have 25 percent of the world’s prisoners.'
