A policewoman who was thrown off her horse at the Justice for George Floyd protest in central London has been hospitalised.
Footage shows the moment the police officer collided with a traffic light, causing her to fall off a horse during the demonstration.
In a statement, the Met Police said 14 arrests were made at the Black Lives Matter protest.
The force said 10 officers were injured at the demonstration after the crowd became "angry and intent on violence" after 7pm.
Superintendent Jo Edwards, spokesperson for policing today's demonstration, said: "We understand people's passion to come and let their voice be heard, they protested largely without incident.
"Our officers have been professional and very restrained, but there was a smaller group intent on violence towards police officers.
"Twenty-three officers have received injuries, doing their job, policing protest over the last few days, and that is totally unacceptable.
"There have been 14 arrests made today, but we expect that number to rise and there will be a post-event investigation carried out."
