Two more people are now in custody in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt in the event. Five people were taken to the hospital for medical care and were later discharged.
Police detained a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that 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 car park for a short time.
