An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which 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 theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Police arrested a 31-year-old man for suspected robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical believed to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
