An additional two individuals are now in custody in connection with 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 man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police arrested a man in his thirties on suspicion of theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
