An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit 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. Before the incident, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the injured during the incident. Five people went to hospital for treatment and were later released.
Police detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of people hurt by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
