An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals went to hospital for medical care and were later released.
Officers detained 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 called at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant spray.
The attack - which police said was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
