An additional two individuals are now in custody related to a theft at Heathrow Airport in which 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 on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of a number of individuals hurt by an irritating chemical thought to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
