An additional two individuals are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Officers arrested a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
