Two more people are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for medical care and were later released.
Police detained a 31-year-old man for suspected robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at approximately 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be pepper spray.
The assault - an event that police said was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
