An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for medical care and have since been discharged.
Police detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding several people hurt by an irritating chemical believed to be pepper spray.
The attack - which 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 T3 car park for a short time.
