An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past 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 those hurt in the event. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police detained a man in his thirties on suspicion of theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
