Two more people are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for medical care and were later discharged.
Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of people injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
