Two more people are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of several people hurt by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
