Two more people have been arrested in connection with a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for treatment and have since been discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of people hurt by an irritating chemical thought to be an irritant spray.
The assault - which police said was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
