An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for treatment and have since been released.
Officers detained a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT following reports of several individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - which police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
