An additional two individuals have been arrested in connection with a robbery 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 arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting 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 were later released.
Officers arrested a 31-year-old man on suspicion of theft and assault near the location. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical believed 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 Terminal 3 parking facility for a short time.
