An additional two individuals are now in custody in connection with a theft at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
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 medical care and have since been discharged.
Officers arrested a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
