An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for medical care and have since been released.
Officers arrested a man in his thirties for suspected robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
