An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police detained a man in his thirties for suspected robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
