Two more people have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained for suspected 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 Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals went to hospital for medical care and were later released.
Officers detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical thought to be pepper spray.
The attack - which police said was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
