An additional two individuals are now in custody related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties on suspicion of theft and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
