Two more people are now in custody in connection with a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for medical care and were later discharged.
Police arrested a 31-year-old man for suspected theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
