An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, 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 are still being held, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for treatment and have since been discharged.
Police arrested a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
