At the second tribunal it was heard former Det Con Sean Brierley went to Gravity Well Taproom on the night of two July 2025 after being advised a suspect at Leyton police station was not but accessible to be interviewed.
In video footage from the east London bar, the Metropolitan Police officer might be seen ordering three glasses of white wine over two hours.
CCTV confirmed Brierley “unsteady on his feet”, “staggering” and “off balance” when he returned to the police station later that night, the panel heard on 12 February.
A custody sergeant gave proof that Brierley had “smelt drunk” and different employees reported his speech had been “slurred”, the ruling stated.
Panel chair Cdr Katie Lilburn wrote: “The fact that the former officer was so intoxicated that he could not walk straight meant that he was unfit to deal with a prisoner in custody, which was the purpose of him being at the police station.”
Mr Brierley’s colleagues had been so involved about his state that they’d organized a welfare examine at his residence later that night time and “found him lying in his bed in a pair of boxer shorts, with the duvet pulled off him”, and stated he “looked very disoriented and was staring at the ceiling in a glazed manner,” the ruling stated.
