An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation 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 parking garage elevator.
A three-year-old girl was among the those hurt during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT following reports of several people injured by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
