An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Police arrested a man in his thirties on suspicion of robbery and assault near the location. He has since been released under investigation while inquiries continue.
Police were alerted at about 08:10 GMT following reports of several individuals injured by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
