The author of the research paper wrote: "The pseudonymous artist Banksy is one of the UK's most successful contemporary artists, but his identity remains a mystery. The model takes as input the locations of these artworks, and calculates the probability of 'offender' residence across the study area."

Experts cross-referenced pubs, parks and residential areas in London and Bristol which identified 10 potential ''Banksys.''

These places were linked to Gunningham, who in 2008 was identified by a newspaper as Banksy.

Steve Le Comber, a biologist and co-author of the study, told the BBC: "I'd be surprised if it's not [Gunningham], even without our analysis, but it's interesting that the analysis offers additional support for it."

"What I thought I would do is pull out the 10 most likely suspects, evaluate all of them and not name any. But it rapidly became apparent that there is only one serious suspect, and everyone knows who it is. If you Google Banksy and Gunningham you get something like 43,500 hits."

"These results support previous suggestions that analysis of minor terrorism-related acts (e.g., graffiti) could be used to help locate terrorist bases before more serious incidents occur, and provides a fascinating example of the application of the model to a complex, real-world problem."

Could the study be true? Or is it simply coincidence that Banksy's site is currently offline.
