An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for medical care and have since been released.
Officers detained a man in his thirties for suspected robbery and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
