Two more people have been arrested related to a robbery at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, 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, authorities confirmed.
These detentions follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals went to hospital for medical care and have since been discharged.
Police arrested a man in his thirties on suspicion of robbery and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of several individuals hurt by an irritating chemical believed to be pepper spray.
The assault - an event that police said was isolated and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
