Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
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 car park lift.
A toddler aged three was among the injured during the incident. Five people went to hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of theft and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT following reports of a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - which authorities stated 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 briefly.
