An additional two individuals are now in custody related to a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and were later discharged.
Police arrested a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of several people hurt by an irritating chemical thought to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
