Two more people are now in custody related to a theft 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 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for treatment and were later released.
Officers detained a man in his thirties for suspected theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance believed to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
