Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Police arrested a 31-year-old man on suspicion of theft and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of a number of people injured by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
