An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for medical care and were later released.
Officers arrested a 31-year-old man for suspected robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of people injured by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
