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, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. Five people were taken to the hospital for medical care and have since been discharged.
Police detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical thought to be pepper spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
