An additional two individuals are now in custody related to a robbery at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after a probe into an attack 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 those hurt in the event. 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 pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The attack - which police said was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
