A Spanish hotel chain is running a competition for stressed executives to let off steam in a fashion usually reserved for rock stars - by smashing hotel rooms.

NH Hoteles says it will allow 30 people chosen by a team of psychologists to help demolish the interior of the 11-year-old NH Alcala hotel in central Madrid as part of its refurbishment.

The hotel chain says the chosen 30, armed with a mallet and hard hat, can destroy any part of the 146-room building, from bringing down walls to smashing windows.

The demolition will take place on July 3.
