An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the injured in the event. A total of five individuals went to hospital for medical care and were later discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of a number of individuals injured by a noxious substance thought to be an irritant spray.
The attack - which police said was isolated and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
