Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for medical care and have since been released.
Officers arrested a man in his thirties on suspicion of robbery and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of several individuals injured by a noxious substance believed to be an irritant spray.
The attack - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
