An additional two individuals are now in custody related to a theft at London's Heathrow Airport where 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 on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for treatment and have since been discharged.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT following reports of a number of individuals injured by a noxious substance believed to be pepper spray.
The attack - which authorities stated was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
