Two more people have been arrested related to a theft at London's Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft 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.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man for suspected robbery and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of a number of individuals injured by an irritating chemical thought to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
