An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Police arrested a man in his thirties on suspicion of robbery 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 several people hurt by a noxious substance thought to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
