An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be pepper spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
