Two more people are now in custody in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for treatment and were later released.
Officers detained a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
