Two more people have been arrested in connection with a theft at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for treatment and have since been released.
Police arrested 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 alerted at about 08:10 GMT after reports came in regarding several people hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
