Two more people are now in custody in connection with a theft at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
