An additional two individuals are now in custody related to a theft at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
