An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers arrested a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be pepper spray.
The attack - which authorities stated was isolated and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
