An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a man in his thirties for suspected robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
