An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by 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 arrested for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting 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.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance thought to be an irritant spray.
The assault - which police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
