An additional two individuals have been arrested related to a theft at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for medical care and were later discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by an irritating chemical thought 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 partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
