An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests 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 parking garage elevator.
A toddler aged three was one of the those hurt in the event. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers arrested a man in his thirties for suspected theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
