An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT following reports of a number of individuals hurt by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
