OJ Simpson has been released from prison after serving nine years for armed robbery.

The former American football player and Hollywood star was jailed for 12 years for a botched hotel-room robbery of sports memorabilia.

He is out on parole, with supervision for another five years.

The 70-year-old was released from a Nevada prison this morning, state authorities said.

Simpson walked free after a murder trial in 1995, after he was acquitted of killing his ex-wife, Nicole Brown Simpson, and her friend, Ronald Goldman in Los Angeles.
