An additional two individuals have been arrested related to a theft at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, 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. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT following reports of a number of individuals injured by an irritating chemical believed to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
