An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people were taken to the hospital for treatment and have since been released.
Police detained a man in his thirties for suspected robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance believed to be an irritant spray.
The assault - which police said was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
