An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
These detentions come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for treatment and were later discharged.
Police detained a 31-year-old man for suspected theft and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
