Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Police arrested a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT following reports of a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
