An additional two individuals have been arrested related to a theft at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-level parking garage at 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. A total of five individuals went to hospital for medical care and were later released.
Police detained a 31-year-old man for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
