An additional two individuals are now in custody related to a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for treatment and were later released.
Officers detained a man in his thirties for suspected robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of a number of people injured by a noxious substance thought to be pepper spray.
The attack - which police said was isolated and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
