An additional two individuals are now in custody in connection with a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained 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. Before the attack, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for medical care and were later released.
Officers detained a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding several people injured by an irritating chemical thought to be pepper spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
