The Met Police confirmed it was called to “a collision with a police officer who was on foot at the eastern end of Constitution Hill next to Buckingham Palace”.
A spokesperson said: “Both the rider of the e-scooter and the police officer were taken to hospital. Their injuries were assessed as non-life threatening and non-life changing.
“The scene of the incident was cordoned off while the level of injuries was confirmed.”
Officers were seen patrolling the cordon and shouted at several cyclists who at one point attempted to pass through a cycle lane within the cordon.
“Get out, you’re in a crime scene,” an officer was heard shouting at the cyclist.
The palace was not flying the Royal Standard, suggesting King Charles was not present at the time of the collision.
