An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to 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 those hurt in the event. A total of five individuals were taken to the hospital for medical care and were later discharged.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by an irritating chemical believed 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 delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
