Two more people have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for medical care and have since been discharged.
Officers detained a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of a number of people hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was a standalone incident 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 Terminal 3 parking facility for a short time.
