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 man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
