Two more people are now in custody related to a theft at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Police detained a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of several people injured by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered 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.
