Two more people are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured in the event. Five people went to hospital for medical care and were later discharged.
Police detained a 31-year-old man for suspected theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT following reports of several people injured by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
