Two more people have been arrested in connection with a theft at London's Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, according to police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Officers arrested a man in his thirties for suspected theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the T3 car park for a short time.
