An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at approximately 08:10 GMT following reports of a number of individuals injured by a noxious substance thought to be an irritant spray.
The attack - which police said was a standalone incident 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 Terminal 3 car park for a short time.
