Two more people have been arrested related to a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and were later discharged.
Police arrested a 31-year-old man for suspected theft and assault near the scene. 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 people hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
