An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties on suspicion of theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of a number of people injured by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated 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 T3 parking facility for a short time.
