An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
