Two more people are now in custody related to 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 police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
