Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for medical care and were later released.
Officers detained a 31-year-old man for suspected theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
