An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery 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 assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for treatment and have since been discharged.
Officers detained a 31-year-old man for suspected robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of a number of individuals hurt 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 delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
