Two more people have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for medical care and were later released.
Officers arrested a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be an irritant spray.
The attack - which police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
