An additional two individuals are now in custody related to a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
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 conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of several individuals injured by an irritating chemical believed to be pepper spray.
The attack - which authorities stated was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
