Two more people are now in custody in connection with a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after 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 three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers detained a man in his thirties for suspected theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT following reports of a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - which police said was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
