Two more people are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries 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, the force said.
The arrests follow a probe into an attack at the multi-level parking garage 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 parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for treatment and have since been released.
Police detained a 31-year-old man for suspected theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
