An additional two individuals are now in custody related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers arrested a 31-year-old man for suspected robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several people injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
