Two more people have been arrested related to a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
