An additional two individuals 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 an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for treatment and were later discharged.
Police detained a man in his thirties for suspected theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of a number of people injured by a noxious substance believed to be an irritant spray.
The attack - an event that police said was isolated and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
