An additional two individuals have been arrested related to a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault near the scene. 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 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 main airport tunnel and the T3 parking facility briefly.
