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 man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the injured in the event. Five people went to hospital for medical care and were later released.
Police arrested a 31-year-old man on suspicion of theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT following reports of a number of people injured by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
