An additional two individuals are now in custody related to a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to police.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for medical care and have since been discharged.
Police detained a 31-year-old man on suspicion of theft and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
