Two more people are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant 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 on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Police arrested a man in his thirties on suspicion of theft and assault near the location. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be pepper spray.
The assault - an event that police said was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
