An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's 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 in the event. A total of five individuals went to hospital for medical care and were later discharged.
Police detained a 31-year-old man for suspected robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance thought to be pepper spray.
The attack - 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 Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
