An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Police arrested a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
