Two more people are now in custody related to a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after a probe 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 had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for treatment and have since been discharged.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
