An additional two individuals have been arrested related to a theft at London's Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The attack - an event that police said was isolated and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
