Two more people are now in custody related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected theft and assault near the location. He has since been released under investigation while inquiries continue.
Police 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 attack - 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 parking facility for a short time.
