An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, 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 were later discharged.
Police detained a 31-year-old man on suspicion of theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
