Two more people are now in custody in connection with a theft at Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of 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 come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people were taken to the hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of several people injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
