An additional two individuals have been arrested related to a theft at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was arrested in the Lambeth area for suspected 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 follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers arrested a man in his thirties for suspected robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
