An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals injured by a noxious substance believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
