An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 this past 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 injured in the event. A total of five individuals went to hospital for medical care and have since been released.
Police detained a 31-year-old man for suspected robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be pepper spray.
The assault - an event that police said was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
