A police horse has died while on duty at the Notting Hill Carnival, according to Scotland Yard.
The 14-year-old chestnut, named Sandown, was described as one of the Met’s “most experienced horses”.
The force said it would investigate after the animal went down at around 9pm on Sunday.
He died at the scene even though he was given emergency treatment.
The force said in a statement: “It is too early to determine the cause of death. An investigation will now follow.
In a tribute to the animal, the Met said: “PH Sandown was donated to the Met in 2015 and his good nature quickly won over the officers. He was the indispensable horse to help new officers grow in confidence as they went through their training. .
“A pro at policing all kinds of events across London, he demonstrated his courage and bravery at numerous football matches, while also being selected to perform in the Mounted Activity Ride at Olympia and the Mounted Musical Ride.
“Police horses are working animals but PH Sandown was also a lovable character full of personality. He loved his food and was always in his pockets looking for treats.
“PH Sandown was a huge part of the Mounted Branch family and much loved. He will be greatly missed by all.
It came after police made 38 arrests by 7.30pm on Sunday, 10 of which were for suspected assaults.
Other alleged offenses included drug possession, criminal damage and possession of offensive weapons.
Two arrests were made for suspected sexual assaults, according to the force.
Millions of people were expected to attend the carnival during the two-day festival, which has had a two-year hiatus due to the pandemic.
As large crowds gathered on Sunday, two people were injured when a bus shelter collapsed in the Ladbroke Grove area.
Several people were seen standing and jumping on top of it before the incident, with onlookers heard gasping and screaming in shock as the group fell to the top of the shelter.
The two people affected suffered minor injuries and did not require further treatment, police said.
