Two more people are now in custody in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt in the event. A total of five individuals were taken to the hospital for treatment and were later discharged.
Officers detained a man in his thirties for suspected robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by an irritating chemical thought to be pepper spray.
The attack - an event that police said was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
