Two more people are now in custody related to a theft at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for medical care and have since been discharged.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be pepper spray.
The assault - an event that police said 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.
