Two more people are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
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 have since been released.
Police arrested a 31-year-old man on suspicion of robbery and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray.
The attack - which police said 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 Terminal 3 parking facility for a short time.
