Police officers were attacked as they tried to eject people from an out-of-control house party at an Airbnb in Manchester.
Up to 200 people who gathered at a rented "holiday property" in Levenshulme were said to have "terrified" neighbours with reported drunken behaviour and excess noise.
A number of the partygoers became violent when officers arrived at the address in Delamere Road shortly before 10.30pm on Friday.
Items were thrown at officers before the property and area were cleared, said Greater Manchester Police.
No arrests were made but police are keen to hear from anyone who attended the party.
An Airbnb spokesman said: “We have zero tolerance for this type of behaviour, have removed the guest from our platform and are providing the host with our full support.
"There have been over half a billion guest arrivals on Airbnb and, with two million people staying on Airbnb on any given night, incidents like this are incredibly rare.”
Detective Constable Chris Henderson said: "Not only had the partygoers duped the home owner into believing there would be far fewer people at the property, the party got out of hand.
"They terrified local residents in their own homes, then reacted with violence towards police officers when they attempted to clear the party.
"This behaviour is simply unacceptable.
"We are currently investigating crimes of violent disorder and will be reviewing CCTV to identify those involved.
"We would like to hear from anyone who has any information that can help police as we attempt to bring those responsible to justice."
Anyone with any information can contact police on 0161 856 6085, alternatively call 101 of Crimestoppers anonymously on 0800 555 111.
