An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area 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 Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for medical care and were later discharged.
Police detained a man in his thirties for suspected theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance thought to be pepper spray.
The attack - which police said was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
