An additional two individuals have been arrested related to a robbery at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Officers arrested a man in his thirties for suspected theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were called at about 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be an irritant spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
