An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for treatment and have since been released.
Police detained a man in his thirties for suspected robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not considered an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
