An additional two individuals are now in custody related to a robbery at Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper 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 on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers arrested a man in his thirties for suspected robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT following reports of a number of individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
