Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions come after an investigation 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 car park lift.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for medical care and were later discharged.
Police arrested a 31-year-old man for suspected theft and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
