Two more people are now in custody related to a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man for suspected theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
