An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
