An additional two individuals are now in custody related to a theft at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people went to hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected robbery and assault near the scene. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT following reports of a number of individuals injured by a noxious substance believed to be pepper spray.
The attack - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
