Videoed is a parked ambulance in front of a police car. An officer is seen between the two vehicles. The person filming says the ambulance was used as a disguise to arrest high school students. Note that the ambulance does not carry a license plate.
Ambulances have been used since the beginning of the 2022 protests to transport personnel discretely and to arrest protestors. This is not a new practice and was utilised during the November 2019 crackdown. However, video evidence shows its nationwide spread.
