Two more people 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 law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people went to hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at about 08:10 GMT following reports of a number of people hurt by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
