Two more people have been arrested related to a theft at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people went to hospital for medical care and have since been discharged.
Officers arrested 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.
Police were called 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 police said was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
