An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police arrested a 31-year-old man for suspected theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT following reports of a number of people hurt by an irritating chemical thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
