Two more people are now in custody related to a robbery at Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after a probe into an attack 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 toddler aged three was among the those hurt in the event. Five people went to hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of theft and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - which police said was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
