An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of 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 treatment and were later discharged.
Officers detained a man in his thirties for suspected theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant 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 temporary shutdown of the main airport tunnel and the T3 car park briefly.
