An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for treatment and were later released.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident 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 car park briefly.
