Two more people are now in custody related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Officers detained a 31-year-old man on suspicion of theft and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of a number of people injured by a noxious substance believed to be an irritant spray.
The attack - which police said was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
