An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for medical care and were later released.
Police arrested a man in his thirties on suspicion of robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
