Two more people have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Police arrested a man in his thirties for suspected theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding several individuals injured by a noxious substance believed to be pepper spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
