An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers detained a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
