An additional two individuals have been arrested related to a robbery at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for medical care and were later discharged.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that police said was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
