Two more people are now in custody in connection with a robbery at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of robbery 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.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a 31-year-old man on suspicion of theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at approximately 08:10 GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The assault - which police said was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
