An additional two individuals are now in custody related to a theft at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police arrested a man in his thirties for suspected theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be an irritant spray.
The assault - which police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
