An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers arrested a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
