An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for treatment and have since been discharged.
Officers detained a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be pepper spray.
The assault - which police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
