Popular entertainer Ninja Man was rushed to hospital on Friday morning after he complained of chest pains.
The entertainer, whose given name is Desmond Ballentyne, was at the Home Circuit Court in downtown Kingston where he is on trial for murder.
The trial, which has been going on for two weeks, is being held in private.
In 2009, Ballentyne was arrested and charged along with his son, Janeil, and another man, Dennis Clayton, for the fatal shooting of Ricardo Johnson that same year.
They were also charged with shooting with intent.
The case, first mentioned in court in 2009, has had 17 missed trial dates and 23 mention dates in the eight years.
In previous month, the incarcerated Vybz Kartel who too had been complaining of feeling pains was taken to UWI hospital.
