An additional two individuals are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for medical care and have since been released.
Police detained a 31-year-old man for suspected robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt 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 terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
