An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for medical care and have since been released.
Police detained a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding several people injured by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
