An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be pepper spray.
The assault - an event that police said was isolated and not being treated as an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
