Mr Helmhout had been arrested for a breach of a protection order and had been transported to the regional watch-house.
On arrival at the watch-house Mr Helmhout was taken from the police van and was escorted to the charge room for processing by the officer in charge of the watch-house, Sergeant John Birch. Also present in the watch-house were the defendant and Constable Andrew Smith. Mr Helmhout was directed to stand on the yellow line in front of the charge counter, a direction he initially complied with. The charge sergeant stood behind the watch-house charge counter and commenced to ask Mr Helmhout some questions regarding his welfare as required when lodging prisoners at the regional watch-house. The defendant and Constable Smith stood on either side of Mr Helmhout in front of the charge counter but they were not restraining him.
During this process Mr Helmhout was somewhat argumentative and appeared to be affected by intoxicating liquor. He walked away from the yellow line and moved in the direction of Constable Smith, who was standing to his left. Constable Smith asked Mr Helmhout to listen and to return to the yellow line. After a short hesitation Mr Helmhout returned to the yellow line. The sergeant continued to ask Mr Helmhout questions and Mr Helmhout continued to talk while this occurred. The sergeant then yelled at Mr Helmhout and told him to shut up. Mr Helmhout continued to talk while standing at the yellow line.
At this time the defendant was standing to the right of Mr Helmhout observing the interaction between Sergeant Birch and Mr Helmhout. About 1.04 am the sergeant took possession of a canister of the OC foam ... from behind the charge desk and deployed it to Mr Helmhout's face from a distance of approximately 1 metre.
In reaction to the spray, Mr Helmhout walked from the yellow line, turned to his right and walked to the rear of the charge room, wiping his eyes and face. The defendant walked to the charge counter and obtained a canister of OC foam. ... Mr Helmhout reached the rear of the charge room and turned to his left. The defendant walked towards Mr Helmhout and raised the canister of OC foam, in her right hand, pointing it in the direction of Mr Helmhout's face. She then lowered the canister and the following brief conversation took place. Constable Apostoloff said, "Are you going to listen now?". Mr Helmhout said, "Go on".
The defendant raised the canister of foam ... in her right hand and deployed it to Mr Helmhout's face, from a distance of approximately one metre. Mr Helmhout then turned away from the defendant, to his right, and walked to the rear of the charge room, wiping his face and eyes. Immediately before he did that, the canister was again raised towards him and lowered, not deployed. Mr Helmhout said, "Oh fuck, that's shit". The defendant placed the canister of OC foam on the charge counter. The sergeant later requested Mr Helmhout to be taken out for decontamination. He apparently refused decontamination and was subsequently escorted from the charge room.
