Two more people are now in custody related to a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage 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 went to hospital for medical care and were later released.
Officers arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals injured by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
