A dawn raid on a home in north London has discovered 35 men bedding down on mattresses in every room except the bathrooms.
Brent council enforcement officers and police entered the converted three-bedroom semi-detached house on Tuesday morning after neighbours complained about overcrowding, anti-social behaviour and fly-tipping.
Eight men were found sleeping in one of the rooms that was decked wall to wall with mattresses. Even the kitchen contained a sleeping area, while another mattress was found under a canopy in the back garden with no protection against the night temperatures.
An investigation is under way to track down the landlord of the unlicensed HMO.
Last week, Brent council voted in new civil penalty measures to fine rogue landlords up to £30,000 for housing law breaches, such as letting out unlicensed properties.
