An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to 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 arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for medical care and were later released.
Officers detained a man in his thirties for suspected theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The assault - which police said was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
