An additional two individuals are now in custody related to a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of 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 a number of individuals injured by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
