Two more people are now in custody in connection with a robbery at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their suitcases after getting out of 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.
Police detained a 31-year-old man on suspicion of theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of several individuals injured by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
