Two more people are now in custody in connection with a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people went to hospital for medical care and have since been released.
Officers detained a 31-year-old man on suspicion of theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
