A mysterious vandal who daubed offensive slogans across the window of an Army careers centre appears to have struck again.

The graffiti menace has caused thousands of pounds in damage at various locations across Canterbury.

People expressed shock as messages reading "F*** the Army" and "ACAB" - thought to stand for "All Coppers Are B*******" - appeared on the centre in St Peter's Street on Thursday.

It was initially thought to be an anti-military and police protest.

But since then, Rochester Cathedral - a landmark dating back 1,400 years - has been branded with the tag: "Teen horniness is not a crime".

The same motto was sprayed on a wall next to a pedestrian underpass near Canterbury West station.

It is the title of a song by actress Sarah Michelle Gellar, taken from the soundtrack to her 2006 film, Southland Tales.

Elsewhere in the city, the bizarre message "Lone wolves are not alone" was plastered across a wall near the University of Kent, alongside a "Circle-A" anarchy symbol.

The question: "Love Yourself A***hole?" has also been daubed next to another foot tunnel near St Stephen's Close.

It is not known who is behind the criminal damage, but the fact it is all in purple paint suggests it could be the work of one culprit.

Police say they are investigating the vandalism to the Armed Forces careers centre.

The window of the neighbouring Barretts car showroom in St Peter's Street is also said to have been defaced with the message: "Rich ***** here". It has since been scrubbed off.

Canterbury City Council spokesman Rob Davies said the graffiti appears to have been sprayed on private property, and the authority does not have the "right or resources" to tackle it.

He added: "If any graffiti is sprayed on public land then it should be reported to Serco on 0800 031 9091.

"Offensive or obscene graffiti is dealt with as a priority."
