An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals went to hospital for treatment and have since been released.
Police arrested a 31-year-old man for suspected robbery and assault near the location. 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 an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
