An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past 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 injured during the incident. A total of five individuals were taken to the hospital for medical care and were later released.
Police arrested a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
