An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for medical care and were later discharged.
Police arrested a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance thought to be an irritant spray.
The assault - 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 parking facility for a short time.
