An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, according to law enforcement.
A man, 24, 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. Both individuals remain in custody, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were called at about 08:10 GMT following reports of several individuals injured by an irritating chemical thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
