An additional two individuals have been arrested related to a robbery at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases upon exiting 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.
Police arrested a 31-year-old man for suspected theft and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several people hurt by a noxious substance believed to be an irritant spray.
The attack - an event that police said was isolated and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
