Two more people have been arrested related to a theft at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them 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 have since been discharged.
Police arrested a 31-year-old man for suspected robbery and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
