Two more people are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for treatment and were later released.
Police detained a man in his thirties on suspicion of theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that police said was isolated and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
