An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, 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 luggage after getting out of a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people went to hospital for treatment and were later released.
Police detained a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several people injured by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
