An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries 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 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for medical care and have since been released.
Police detained a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT following reports of a number of people hurt by a noxious substance believed to be an irritant spray.
The attack - which police said was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
