An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit 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 on Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for treatment and have since been released.
Police arrested a 31-year-old man on suspicion of theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
