An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for treatment and were later discharged.
Police arrested a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of several people hurt by an irritating chemical thought to be an irritant spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
