An additional two individuals 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 pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers detained 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.
Authorities were alerted at about 08:10 GMT following reports of several individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that police said was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
