An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Police arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of several people hurt by an irritating chemical thought to be pepper spray.
The attack - an event that police said was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
