Two more people have been arrested related to a theft at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for medical care and were later released.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
