An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for treatment and were later discharged.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance thought to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
