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, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for treatment and were later released.
Officers arrested a 31-year-old man for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of several people hurt by a noxious substance thought to be pepper spray.
The assault - an event that 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 briefly.
