An additional two individuals have been arrested 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 man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of 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 this past Sunday. Before the incident, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
