PC Hill said: “I approached him and he appeared very angry and was talking to himself.
“When I identified myself as a police officer he initially ran but then turned to face us and threatened to ‘chop us up’.
“It was rush hour so the roads were very busy. We knew we had to get a grip of him quickly as there was a clear danger to the public.
“He was running full pelt past the Children’s Hospital until we caught up with him in Constitution Hill.
“I’m just pleased we managed to get hold of him pretty quickly and no-one was hurt.”
PC Carnall, who has been with the force for 20 years, said he had represented the force the police’s cross-country running championships thsi year.
He said: “It keeps me in shape and helps me keep up with the crooks.
“I remember him looking over his shoulder at one stage and appearing shocked I was gaining on him.
“That’s when he turned and threatened to chop me with the machete.
PC Stuart Hill receiving his Chief Constable’s Commendation
“There were a lot of people about; we were shouting at them to get out of the way and stay safe.
“I was concerned he may try to take a swing at someone or hold someone hostage.
“We had no idea what his intentions were.
“He was getting tired, I caught up with him and swept his legs away before handcuffing him.
“As we were walking back to our police car I remember quite a few people clapping us in the street and saying well done.
“It’s nice to know the public appreciate our efforts to keep them safe.”
Sergeant Dominic Livesey said: “This was a scary, violent situation that could have ended very differently and with injury to members of the public had the PCs not responded so bravely and brought the incident to a swift conclusion.
“They acted without hesitation for their own safety to arrest an armed and violent suspect.
“The safety of the public was their first thought.”
