Security guards did not record an incident where a patient — who later jumped to his death from a window at the Mater Hospital — was accused of stealing drugs, a court has heard.
A preliminary hearing into the death of Christopher William Boyle (44), who had a history of mental illness, heard the security staff did record other incidents, including details of a man falling asleep in reception.
The hearing was also told there was no CCTV footage of Mr Boyle being ejected from the premises as there was no recording facility connected to the cameras outside the building.
The Belfast Trust has been asked to provide a statement from the company which installed the system to verify this. Mr Boyle, who lived on the Cliftonville Road in north Belfast, died on December 16, 2008.
The court also heard there is footage of the moment he fell to the ground and the moments after, but the footage does not show Mr Boyle as he jumped out of the window.
At an earlier court hearing, it emerged his family is suing hospital bosses for alleged medical negligence.
