Two more people are now in custody in connection with a robbery at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women were robbed of their luggage upon exiting a car park lift.
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 arrested a 31-year-old man for suspected theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
