Two more people have been arrested 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 police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people went to hospital for treatment and have since been released.
Officers arrested a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
