An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police arrested a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at about 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
