An additional two individuals are now in custody related to a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for medical care and have since been released.
Police detained a man in his thirties for suspected theft and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be an irritant spray.
The assault - which police said was isolated and not being treated as an act of terror - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
