An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for medical care and have since been released.
Police arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released under investigation while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
