Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for treatment and were later released.
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 as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals hurt by a noxious substance thought to be an irritant spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
