Sean Levert, who formed 1980s US pop group LeVert with his brother Gerald, has died in hospital after falling ill in prison.

The 39-year-old was taken to an Ohio hospital on Sunday when he became ill in a Cleveland jail.

Levert, the son of O'Jays vocalist Eddie Levert, had been sentenced to serve one year and ten months in prison for failing to pay thousands of dollars in child maintenance.

An autopsy has proved inconclusive, police said, but any suggestion of murder has been comprehensively ruled out.

Jail warden Kevin McDonough said guards had been observing Levert, who suffered from high-blood pressure for several days after he complained of hallucinations.

"There was nothing that would show any of this," he said. "He had an illness while he was here and it turned into an emergency at that time."

Toxicology reports could take more than a month to be completed, the warden added.

LeVert – comprised of brothers Sean and Gerald and their friend Marc Gordon – had a UK top ten hit with Casanova in 1987.

Eddie Levert, 65, has lost both his sons within the last two years. Gerald Levert died aged 40 in 2006 after an overdose of prescription drugs.
