Two more people are now in custody in connection with a robbery at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected theft and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical thought to be pepper spray.
The assault - an event that police said was a standalone incident and not considered 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.
