An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance believed to be pepper spray.
The attack - which authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
