An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage 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 man in his thirties on suspicion of theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
