An additional two individuals have been arrested related to a robbery 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 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for treatment and were later discharged.
Officers detained a man in his thirties on suspicion of theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals hurt by an irritating chemical thought to be pepper spray.
The assault - which 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 parking facility for a short time.
