An additional two individuals are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for treatment and were later discharged.
Police detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several individuals hurt by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
