An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to police.
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 are still being held, the force said.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for medical care and were later discharged.
Officers detained a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
