An additional two individuals are now in custody related to a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected theft and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of people injured by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
