An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and have since been discharged.
Police 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 approximately 08:10 GMT following reports of a number of individuals hurt by an irritating chemical thought to be pepper spray.
The assault - an event that police said was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
