Two more people are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people went to hospital for treatment and were later released.
Officers detained a man in his thirties on suspicion of theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
