This is the shocking moment a man brutally kicked a police officer in the head before he was Tasered.
Police were trying to hold another man down to the ground as he appeared to try and resist arrest at the time of the incident.
As the officers wrestled with the man on the ground, the second man came running over and kicked one of the officers.
Dramatic footage shows how police Tasered the culprit, leaving him motionless on the floor, and then threatened to Taser the man they had been trying to detain - who eventually gave in and dropped to his knees with his hands in the air.
The incident happened at a bar and snacks area of the Manchester Arena on September 2 before footage emerged on X, formerly Twitter, yesterday.
Greater Manchester Police have since confirmed a 42-year-old man and 18-year-old man were arrested on suspicion of common assault of an emergency worker and taken into custody for further questioning. The men have since been bailed pending further investigation as police continue to appeal for information and witnesses.
