An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an attack 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 parking garage elevator.
A toddler aged three was among the injured during the incident. Five people went to hospital for medical care and have since been released.
Police arrested a 31-year-old man for suspected theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT following reports of several individuals injured by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
