An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of several people injured by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
