Two more people are now in custody related to a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected robbery and assault near the scene. He has since been 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 believed to be pepper spray.
The assault - which authorities stated was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
