An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people 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 near the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
