Two more people are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for medical care and were later released.
Police detained a 31-year-old man on suspicion of theft and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several people hurt by a noxious substance believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
