Two more people are now in custody related to a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals 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, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. Five people were taken to the hospital for treatment and have since been released.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT following reports of a number of individuals hurt by a noxious substance believed to be pepper spray.
The assault - which police said was isolated 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.
