An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
