An additional two individuals are now in custody related to 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 arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation 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 car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for medical care and were later released.
Police detained a 31-year-old man for suspected robbery and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several people hurt by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
