An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers detained a man in his thirties on suspicion of theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
