An additional two individuals are now in custody in connection with a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
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 arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding several people hurt by a noxious substance thought to be an irritant spray.
The assault - which police said was isolated and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
