An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people went to hospital for medical care and have since been released.
Police detained a 31-year-old man on suspicion of theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Police were called at about 08:10 GMT following reports of a number of people hurt by a noxious substance thought 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 partial closure of the main airport tunnel and the T3 car park for a short time.
