An additional two individuals have been arrested related to a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by a noxious substance thought to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
