An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
