Two more people have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for treatment and were later discharged.
Police detained a 31-year-old man on suspicion of theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
