Two more people are now in custody in connection with a theft at London's 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 taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for treatment and have since been discharged.
Police detained a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of several individuals hurt by a noxious substance thought to be pepper spray.
The attack - which police said was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
