The young man had been enjoying a night out with friends in Glasgow city centre but decided it was time to change venues.
Unprovoked, he began arguing with the nightclub's bouncer and two police officers before suddenly becoming violently aggressive.
Within moments the police have the clubber in a safe restraint but he is still kicking and lashing out, so back up is called for.
Two plain clothes cops, two more uniformed officers and a patrol car join the scene.
From a bystander's position the restraint looks frightening but the hold is designed to be as much for the young man's safety as for the police.
While three officers hold his body, two more tie his legs at the knees and ankles.
A fifth gently but firmly holds his head. The officer constantly talks to the man, explaining exactly what is happening and that he is trying to stop the man banging his head on the pavement.
After just a few minutes the man is helped to sit up, then stand, before being carried to the waiting police car.
Quick action - working to curtail a situation before real trouble starts - like this is partially credited for falling crime rates in Glasgow's busy city centre.
These are the crimes that worry us the most - and the numbers are all down.
Muggings, assaults and sexual attacks are all on the wane in the area framed by the Clyde to the south, the M8 to the west and north and High Street and Saltmarket to the east.
There were 104 robberies or attempted robberies in Glasgow's main commercial and retail district between April 2012 and March 2013. That was down from 122 a year before and 368 in 2007-2007.
Muggings or attempted muggings, once a daily occurrence, have fallen more than 70% since the Evening Times began its Crime on Your Streets series.
Serious assaults - the most common violent crime - have also plummeted in the city centre. Last financial year there were 109 such crimes recorded. That is down from 183 in 2011-12, and means incidents have almost halved from 327 in 2006-2007.
On Friday and Saturday nights, high visibility policing is the name of the game.
Hundreds of officers are deployed to the city centre - including the busy beats around Central Station, Sauchiehall Street and Queen Street.
And cooperation with bouncers is also helping to curtail night-time crime.
Chief Inspector Alan Porte, Area Commander for the city centre, said: "We can't take the credit for everything but we are clearly doing things right. The city centre is a far safer place to be than it once was.
"Our officers are trained to look for trouble starting and to stop it before it escalates.
"We also have a very good relationship now with bouncers, who are highly trained and very skilled at spotting trouble and getting us involved.
"If we can intervene in an argument before it turns into a fight and send the two parties on their separate ways then we've done our job."
Police are increasingly cracking down on offences such as public drinking and public urinating - resulting in the overall rate of recorded crime in the city centre edging up even as serious offending falls.
Their theory is that stop-and-search activity and a zero tolerance to drunk nuisance crime deters the nastier stuff.
This high-visability policing in the city centre comes despite evidence suggesting falling footfall in the area.
There is no perfect way of measuring how many people are in the centre at any time. The council has four sensors installed at key points on the "Golden Z" of Sauchiehall, Buchanan and Argyle Streets. They recorded footfall down about 8% in the second half of 2012, including the all-important Christmas period, compared with they same six-month period in 2011.
Trouble in Glasgow may be down. But it is not down in every beat in the city centre - suggesting some offending is moving.
Historically the area around - but not inside -Central Station has been Glasgow's businest beat.
But the location has been replaced as the busiest beat in recent years by Alpha Bravo 6, an area that includes Queen Street and the bottom part of Buchanan Street.
The block had 3740 offences in 2012-13, up from 3494 in the year before.
That sounds bad. But the number of serious crimes in the area has fallen.
There were just seven robberies or attempted robberies in the beat in 2012-13, compared with 19 the previous year and 33 back in 2006-2007.
The number of people caught urinating in public in the beat has risen tenfold in seven years, from 57 in 2006-2007 to 539 last year.
