Witnesses claimed he went upstairs in the building and suddenly began smashing an office window on the second floor with a chair. He then attempted to climb out of the window but caught his clothing on the jagged glass, lost his footing and fell to the pavement below. One eyewitness said: “Security or police were chasing him and he managed to get inside the shop and upstairs where he used the chair to smash the window of the shop. He started to climb out, but fell and somersaulted through the air where he landed on his back. He looked in a bad way to me.” Footage of the incident has emerged online and shows how the injured man appeared to catch his leg on the ledge before tumbling downwards. Police described his injuries as 'life-threatening' and said he continued to be in a critical condition this morning.
