Two more people are now in custody in connection with a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and have since been released.
Officers detained a man in his thirties on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several people hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
