An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers arrested a 31-year-old man on suspicion of theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
