An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Police detained a 31-year-old man on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding several people hurt by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
