An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among 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 theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
