Two more people are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers detained a man in his thirties on suspicion of robbery and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
