Rapper Sean 'Diddy' Combs was hospitalised after suffering a head injury while serving his prison sentence, according to a report. The injury was described as non-life-threatening, but details about how it happened were not immediately available. Combs has been behind bars since his sentencing in a criminal case that attracted wide public attention. Inmates who need treatment beyond what a facility clinic provides are commonly taken to outside hospitals. It was not stated how long he would remain under medical observation or what tests he would undergo. The report of the hospital visit spread quickly, given how closely his case has been followed since his arrest and trial. It remained unclear whether authorities would release further information about his condition.
