An additional two individuals have been arrested in connection with 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 Lambeth for suspected robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
