An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to 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 remain in custody, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for medical care and were later released.
Police detained a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
