Two more people are now in custody related to a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people were taken to the hospital for medical care and have since been released.
Officers detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 08:10 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 a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
