An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases 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 medical care and were later discharged.
Police arrested a 31-year-old man for suspected theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray.
The assault - which police said was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
