Update: After 9years, Former US football star OJ Simpson has been released on parole from a jail in Nevada

Former US football star and actor OJ Simpson has been released on parole after nine years in a Nevada jail.

He had been serving time for armed robbery, assault with a deadly weapon and 10 other charges over a 2007 confrontation at a Las Vegas hotel.

Simpson was approved for early parole release in a board hearing in July. In 1995 he was infamously acquitted of the murder of his ex-wife Nicole Brown Simpson and her friend Ron Goodman.

Simpson signed his exit papers and was then released from the Nevada Correctional Center just after midnight ... minutes after he was eligible to be paroled.  The release was stealth, because prison officials wanted to avoid a media crush.

As he walked out, he was told by prison staff, "Don't come back" ... it's a standard issue farewell.  The 70-year-old convict replied, "I don't intend to."

A driver was waiting to whisk Simpson away.  For now he'll be staying somewhere in Nevada ... he want to live in Florida but the paperwork hasn't been processed.  Florida Attorney General Pam Bondi is trying to block the move.

Simpson, who served 9 years for a kidnapping conviction, wore standard prison issue on his way out ... blue jeans, a denim jacket and white tennis shoes.
