An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area 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.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
