Video shows the security worker grabbing the punter by the arm and swinging him around onto the ground while trying to eject him.
Another punter can be heard shouting: “What are you doing? What are you doing you k**b.”
As the man stumbles and tries to get up, the security guard then appears to punch him and kick him.
The bouncer, who is wearing a Pro-Tect vest, then keeps the man in a head lock as the man holds onto his leg.
Another punter then tries to step in and diffuse the situation but the bouncer then grabs continues holding onto the man and swings him onto the floor.
As the man is laying on the group, the guard puts his arm back around the man’s neck to keep him still before hitting him twice.
The clip then ends after another reveller steps in to stop the incident and drunken cheers can be heard in the background.
Pro-Tect Security today revealed that the employee has been dismissed following the incident.
They also said the bouncer had only been working two shifts with them when the incident happened at Park Lane on Saturday.
Speaking today, Louise, who captured the footage, said: “I didn’t actually see what had happened beforehand, I just noticed the bouncer throwing his weight around and thought I should get the evidence.
“Some people were shocked, some were cheering it in although I’m not sure why.
“Interaction with the bouncers there is usually okay. Some of them throw their weight around a bit more than others, however, this incident was next level.
“I’m sure whatever happened beforehand didn’t warrant that level of force, the guy didn’t try and fight back once.
“I’ve managed to find out that he is mainly okay, quite a few aches and pains though which I’m not surprised about.”
Louise posted the video onto social media yesterday, writing: “How is this even okay?
“Park Lane smoking area last night.”
The post has been viewed over 14,000 times and attracted over 300 comments from shocked social media users.
Terry Court said: “Wtf that’s horrible.
“Un-f******-real, been like that for years I hear on the strand.
“I agree if someone’s being anti-social then use that amount of force, but that’s too much.
“We all wonder why the [Torquay] bay is the way it is, people with a uniform use it for power more than code of conduct.”
Elise J Groves said: “Pro-Tect Security hope you sacked him, that’s disgusting.”
Nick Chalk said: “If that’s my mate and I’m the lad on the side of him he’s getting the biggest smash in his jaw the f*****g little scumbag.”
Skye Adams added: “I would’ve booted that fat c***.
