An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people went to hospital for medical care and were later released.
Police arrested a man in his thirties on suspicion of theft and assault near the location. 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 hurt by a noxious substance thought to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
