An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which over twenty individuals 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 for suspected theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and were later discharged.
Officers detained a man in his thirties on suspicion of theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be pepper spray.
The attack - which police said was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
