An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt in the event. A total of five individuals were taken to the hospital for treatment and were later released.
Officers arrested a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of several people hurt by an irritating chemical believed to be pepper spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
