An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a 31-year-old man for suspected theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of a number of people hurt by an irritating chemical thought to be pepper spray.
The assault - an event that police said was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
