An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals went to hospital for medical care and have since been discharged.
Police detained a man in his thirties for suspected robbery and assault near the location. 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 several individuals injured by a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
