An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for medical care and have since been released.
Officers arrested a 31-year-old man for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
