An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of 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.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people went to hospital for medical care and were later discharged.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of several people hurt by an irritating chemical believed to be pepper spray.
The assault - which police said was isolated and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
