An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people went to hospital for treatment and have since been discharged.
Police detained a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be pepper spray.
The assault - which police said was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
