Two more people have been arrested in connection with a robbery at 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 the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Police arrested a man in his thirties for suspected theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of a number of individuals injured by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated 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.
