An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for treatment and have since been released.
Police arrested a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding a number of people injured by a noxious substance thought to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
