Two more people are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of 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 follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for treatment and were later discharged.
Police arrested a 31-year-old man for suspected theft and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be an irritant spray.
The attack - which police said was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
