An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for treatment and were later discharged.
Police detained a 31-year-old man for suspected theft and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals hurt by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
