An additional two individuals have been arrested related to a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
These detentions follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for treatment and were later released.
Officers detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance believed to be an irritant spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
