An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before 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 were later discharged.
Police arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
