An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected robbery and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of a number of people injured by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
