An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for medical care and have since been discharged.
Police detained a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding several people injured by an irritating chemical believed to be pepper spray.
The attack - which police said was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
