Two more people have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the those hurt in the event. Five people went to hospital for treatment and were later discharged.
Officers detained a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT following reports of several people hurt by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
