Two more people are now in custody related to a robbery at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured during the incident. Five people went to hospital for medical care and were later released.
Officers arrested a man in his thirties for suspected robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical thought to be an irritant spray.
The assault - an event that police said was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
