An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT following reports of a number of people hurt by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
