An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth for suspected 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 attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of several individuals hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
