An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
