Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries 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 woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for treatment and have since been discharged.
Police detained a 31-year-old man on suspicion of theft and assault near the scene. He has since been released under investigation while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
