Two more people have been arrested related to a theft at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt 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 for suspected robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of a number of 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 considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
