US actor Chris Penn, younger brother of Oscar-winner Sean Penn, has passed away.
Police said they discovered the 40-year-old actor's body at around 4pm at an apartment near the Pacific Ocean in the Los Angeles suburb of Santa Monica yesterday.
No cause of death was immediately determined but there was no signs of foul play, the sources added.
A family spokeswoman confirmed the death and said the Penn family "would appreciate the media's respect of their privacy during this difficult time."
Penn, 43, was a character actor who appeared in dozens of films including "Reservoir Dogs," "Mullholland Falls" and the 2004 film "Starsky & Hutch."
In one of his best known roles, he played baby-faced criminal Nice Guy Eddie Cabot in director Quentin Tarantino's "Reservoir Dogs." He also starred along with his brother in the 1986 film "At Close Range."
Recently, Penn voiced Officer Eddie Pulaski in the video game "Grand Theft Auto: San Andreas."
