An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers 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 were taken to the hospital for treatment and have since been discharged.
Police detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of individuals injured by a noxious substance thought to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
