An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. Five people were taken to the hospital for treatment and were later released.
Officers detained a 31-year-old man for suspected robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was a standalone incident and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
