According to TMZ.com, sources at the Cuyahoga County Jail where R&B singer Sean Levert was detained for non-payment of child support, say Levert may have been under the influence of an unknown substance and had to be physically restrained by corrections officers.

Levert lost consciousness sometime after being restrained. He was taken to a local hospital where he was pronounced dead. Levert had a history of high blood pressure according to his family.

    Staff at the Cuyahoga County Jail tell us Levert was “out of control” and “hallucinating,” forcing them to place him in a restraining chair, because he was a danger to himself. The jail’s warden Kevin McDonough says Levert was cooperative and “went willingly” when jail staff bound his wrists and shackled his feet.The Cuyahoga County Coroner tells us Levert’s body showed no signs of physical trauma, nor do they suspect foul play. They are currently awaiting toxicology results — those will take four to six weeks to come back. (Source)
