An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow 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 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.
Officers arrested a 31-year-old man for suspected theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT following reports of a number of people injured by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
