Two more people have been arrested related to a robbery at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement. A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed. These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift. A toddler aged three was among the injured during the incident. Five people were taken to the hospital for medical care and were later released. Police arrested a man in his thirties for suspected theft and assault close to the scene. He was subsequently released under investigation while inquiries continue. Authorities were called at about 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical thought to be pepper spray. The assault - an event that police said was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
