An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Police detained a 31-year-old man on suspicion of theft and assault near the location. He has since been released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
