An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers arrested a man in his thirties for suspected theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
