A post mortem on Thursday showed that an 18-year-old male detainee who died in his cell at the central prison had choked on his own vomit.
The man, Andreas Sofroniou from Limassol, who was on remand in connection with burglary and theft, was found unconscious in the cell he shared with his uncle at 4.30am Wednesday.
Wardens and nurses tried but failed to resuscitate him.
According to state pathologist Sofoclis Sofocleous, who carried out the post mortem, Sofroniou had suffocated to death by inhaling his own vomit.
He added that toxicology tests will indicate whether Sofroniou had used drugs prior to his death.
Sofocleous said he could not be sure of what caused Sofroniou to vomit, as this is something that could happen to anyone for any reason.
Police had ruled out foul place and suicide.
Main opposition Akel raised a question on Wednesday as to why Sofroniou was detained in the same ward as convicts.
According to the Cyprus News Agency, the 18-year-old had requested in writing to be allowed to move into the same holding cell as his paternal uncle in the convicts’ ward.
His request was approved by the mental health services.
