Two more people are now in custody related to a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for medical care and have since been released.
Officers detained a man in his thirties for suspected theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
