An additional two individuals are now in custody related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for medical care and have since been discharged.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical believed to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
