An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of 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 come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the those hurt in the event. Five people went to hospital for treatment and were later released.
Police arrested a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance thought to be pepper spray.
The attack - 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 briefly.
