Two more people are now in custody related to a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the injured in the event. Five people went to hospital for treatment and have since been discharged.
Police detained a man in his thirties on suspicion of theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of a number of people hurt by an irritating chemical believed to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
