Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, two women were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
