Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals went to hospital for medical care and have since been discharged.
Police arrested a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT following reports of a number of people injured by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
