An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a man in his thirties on suspicion of robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
