Two more people have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Officers detained a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals injured by a noxious substance thought to be pepper spray.
The assault - which authorities stated was isolated and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
