An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Officers arrested a 31-year-old man for suspected theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated 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 for a short time.
