Two more people are now in custody related to a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody 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. Both individuals remain in custody, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the those hurt in the event. Five people were taken to the hospital for treatment and were later released.
Police detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be pepper spray.
The attack - which authorities stated was isolated and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
