But although 50 people were arrested, mainly for public order offences, and there were a number of isolated incidents of serious disorder, much fewer people took part in the demo which started at 6pm in Trafalgar square than police, who feared up to 1,800 may turn up, anticipated.
Several people remained in custody this morning.
Police said the majority of arrests were made following two containments in the areas of St Martin’s Place, Trafalgar Square and Parliament Street, Whitehall.
Three officers were taken to hospital with injuries sustained policing the protests, the injuries are not believed to be life-threatening.
One man was arrested for assaulting a police officer in connection with one of the incidents where an officer was injured and he remains in custody at central London police station.
A Met Police spokesman said: “During the course of the evening, a police horse suffered injuries near Buckingham Palace in which the police rider was thrown from the horse.
“The rider was taken to hospital as a precaution and the horse returned to stables for treatment.”
A stop and search carried out at 2.25pm, hours before the demo, found three men acting suspiciously to have on them knives, smoke and paint bombs, gas canisters and lock picks.
Thousands of people wore sinister Guy Fawkes masks
“I’d like to thank those who conducted themselves in a peaceful manner and as well as Londoners for their patience and tolerance whilst anti-social and intimidating behaviour was happening.”
He added: “Officers have been hospitalised, a police horse suffered injuries and a police car was criminally damaged during the course of the protest which is completely unacceptable.

“I praise the professionalism and restraint that officers have shown in the face of hostile provocation and enabled the policing operation to pass without major incidents. We will bring those responsible for the criminality to face justice.”

The initially peaceful Million Mask March soon turned ugly as thousands of demonstrators wearing Guy Fawkes masks clashed with barriers of police officers and hurled fireworks.
Protestors were met by a “significant policing operation” as thousands of extra officers were deployed to tackle the unrest.
Violence also reportedly erupted near Buckingham Palace – a long way from the agreed route.
Bloodied bodies were tended to by emergency crews as police and mounted officers formed human shields on sections of Westminster closed off to surging protesters.
Some managed to break free from the main route, heading instead to Buckingham Palace and Green Park, where protesters threw missiles such as cones and fireworks at police horses.
She said: “There are people who aren’t represented, they should be here. I am the people.
“The media twist it. We are peaceful, we are doing this in a peaceful manner, but the media focus on the 1% who cause trouble.”
Self-proclaimed anarchist Aztecarna Peatonito, from Mexico, said he wanted a peaceful way of spreading a message against inequality.
He said: “We tried for six years to get the press to take us seriously. It is only when we wore the masks that we started getting attention.
“Anyone who is violent is not with us.”
Videos posted to YouTube last night and today showed some people on the march banging on car windows and intimidating drivers along the route who did not support them.
Ahead of the demo, on Wednesday, police issued a desperate plea for the mystery organisers of what has been described as one of “the world’s biggest ever global protests” to contact them amid fears of carnage in London and other cities across the globe.
Skum Tek, which organises the illegal raves and has previously promoted Anonymous and the Occupy movement on its Facebook page, had also planned a rave on the night of November 5 at an undisclosed location in the capital.
A flyer, which was doing the rounds on Facebook called it the: “Scumpowder N Reason Lost the Plot rave featuring a picture of the Gunpowder Plot conspirators with Guy Fawkes head replaced as a skull and cross bones with a Scum Tek logo on the forehead.
No venue was listed, but it was reportedly due to start at 8pm.
However, the group has since denied it ever intended holding an event last night.
