An additional two individuals have been arrested related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for medical care and have since been discharged.
Officers detained a 31-year-old man for suspected theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be an irritant spray.
The assault - which police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
