An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt in the event. Five people went to hospital for treatment and have since been discharged.
Police arrested a 31-year-old man for suspected theft and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
