An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions follow an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a 31-year-old man on suspicion of theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be pepper spray.
The attack - which authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
