An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people sustained injuries 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 woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. A total of five individuals went to hospital for treatment and have since been released.
Police arrested a 31-year-old man for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of a number of people injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
