The 40-year-old British-born actor, presenter and model - whose sister is June Sarpong - has reportedly taken his own life by jumping from a bridge in Pasadena, California.

His family told Us Weekly in a statement: "It is with great sadness that the family of Samuel Sarpong Jr. must share the news that Sam has passed away. The circumstances surrounding his death are currently under investigation and no additional details are known at this time. ... The family appreciates the thoughts and prayers and other expressions of sympathy, and request that privacy be respected at this extremely difficult time."

Police were reportedly called to the scene after Sam, who co-hosted MTV's 'Yo Mamma' with Wilmer Valderrama, was spotted standing outside the bridge railing.

Police Chief Phillip Sanchez said: "It is sad and troubling when an individual has become so despondent that he or she feels their only option is to end their life. These incidents can often have a significant impact on the victim's loved ones, first responders, and the community as a whole. My prayers go out to the family."

Sam's management company, Advanced Management, tweeted: "Devastated to hear that our friend and client @mrsamsarpong is no longer with us. Prayers and thoughts to the entire Sarpong family."

Sam modelled for Tommy Hilfiger, Gucci and Versace.

He also made fashion history by becoming the first black model to do a Louis Vuitton editorial campaign.

Sam had acting success in 'Veronica Mars', 'Bones', 'Everybody Hates Chris', 'Cold Case' and a small part in the upcoming 'American Crime Story'.
