Two more people are now in custody related to a theft at London's Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Police 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 hurt by an irritating chemical believed to be pepper spray.
The attack - which police said was isolated and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
