An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where 21 people 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 for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women were robbed of 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 released.
Officers detained a 31-year-old man on suspicion of theft and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at about 08:10 GMT following reports of a number of individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was isolated and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
