An additional two individuals are now in custody related to a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for treatment and were later discharged.
Officers arrested a man in his thirties on suspicion of robbery and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
