Two more people are now in custody in connection with a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. Five people were taken to the hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT following reports of a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
