An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a man in his thirties for suspected robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be pepper spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
