An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested 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.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for medical care and were later discharged.
Police arrested a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance thought to be an irritant spray.
The attack - which police said was a standalone incident and not considered terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
