An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for medical care and have since been released.
Officers arrested a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The assault - which police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
