An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant 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 on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Officers detained a man in his thirties for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
