Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for treatment and were later released.
Police detained a man in his thirties for suspected theft and assault close to the location. He has since been released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
