An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of several individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
