An additional two individuals have been arrested related to a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
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 have since been discharged.
Police detained a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted 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 assault - an event that authorities stated was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
