Two more people are now in custody related to a theft at London's Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for treatment and were later discharged.
Officers arrested a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted 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 pepper spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
