Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant 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. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
