An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for treatment and have since been released.
Officers detained a man in his thirties for suspected theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The assault - an event that police said was isolated and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
