Two more people are now in custody in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of 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 discharged.
Officers detained a 31-year-old man for suspected theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of a number of people hurt by a noxious substance thought to be an irritant spray.
The attack - an event that police said was isolated and not being treated as an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
