Or at least there was:
A Scotland Yard spokesman said they were working with gallery staff to ensure they do not "break the law or cause any offence to their visitors."
On the first point - that's great, working to uphold the law is what the police are there for. Although I'd like to hope that this is clearly a case where art is clearly not the same thing as pornography.
On the seond point - what the fuck? Since when does art have _any_ obligation to avoid causing offence?
