Two more people have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted 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 pepper spray.
The assault - which police said was a standalone incident and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
