Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to 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 has since been released pending further inquiries while inquiries continue.
Authorities were called at about 08:10 GMT after reports came in regarding several people hurt by an irritating chemical believed to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
