Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for medical care and were later discharged.
Officers arrested a 31-year-old man for suspected robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
