An additional two individuals are now in custody in connection with a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - which police said was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
