The woman was seen at about 22:20 GMT by Burnard and Davarian on the third floor of the multi-storey car park which overlooks the police station.
The IOPC said both officers were seen on CCTV looking in the direction of the woman, who could be heard singing and shouting, as they made their way into the police station and neither attempted to engage with her.
About nine minutes later, after being alerted to the situation by another officer, the officers left the station where she was last seen and as they tried speaking to her, she fell.
Campbell said it was essential for a police officer to be honest and provide accurate information and, by providing incorrect information, Davarian risked “seriously undermining” the public’s confidence in the police force.
The IOPC said the investigation began in October 2023 and concluded in February 2025, which determined the officers had a case to answer for gross misconduct.
