Two more people are now in custody related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an attack 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 suitcases after getting out of a parking garage elevator.
A toddler aged three was among the those hurt in the event. Five people went to hospital for medical care and were later discharged.
Police detained a 31-year-old man on suspicion of theft and assault near the scene. He has since been released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical thought to be pepper spray.
The assault - which police said 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 Terminal 3 parking facility briefly.
