An additional two individuals are now in custody related to a theft at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for medical care and were later discharged.
Police detained a man in his thirties for suspected robbery and assault close to 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 individuals hurt by a noxious substance believed to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
