An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was one of the injured in the event. Five people went to hospital for medical care and were later released.
Police arrested a man in his thirties for suspected robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - which police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
