An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by 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 conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for medical care and have since been discharged.
Officers detained a 31-year-old man on suspicion of theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
