Two more people have been arrested related to a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Police arrested a 31-year-old man for suspected theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
