An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit 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 Heathrow's Terminal 3 on Sunday. Prior to the incident, 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 those hurt during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
