An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been discharged.
Officers arrested a man in his thirties for suspected theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
