Two more people are now in custody related to a theft at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for medical care and have since been released.
Police detained a man in his thirties for suspected robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of individuals hurt by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
