Two more people are now in custody related to a robbery at Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Police arrested a 31-year-old man for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people injured by an irritating chemical thought to be an irritant spray.
The assault - which police said was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
