An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police detained a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of 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 main airport tunnel and the Terminal 3 car park briefly.
