An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt in the event. Five people went to hospital for treatment and have since been discharged.
Police detained a man in his thirties for suspected robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The assault - an event that police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
