An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for medical care and were later discharged.
Police detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several individuals hurt by an irritating chemical believed to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
