Police are hunting a prolific tagger who has been leaving his mark at Norwich railway station.

Graffiti was sprayed on walls, pylons and trackside property at the station and along a mile of track between Saturday, April 3, and Tuesday, April 6.

Sgt Andy Cook, of British Transport Police, said thee word QUIR featured in the designs. Graffiti artists, or taggers, use ornate signatures called tags to distinguish their work.

Bt Sgt DCook said: 'Graffiti tagging results in substantial costs for the railway industry in terms of repairs and clean-up costs.

'We will do everything in our power to catch those responsible and, working with Norfolk police and our railway industry partners, we will also seek the strongest court penalties for the perpetrators of such crimes."

Sgt Cook said those who tagged trackside property also ran the risk of injury.

"The railway is a dangerous place and people who take the risk of illegally trespassing to commit graffiti offences are also putting their personal safety at risk,' he said.

Officers are also investigating other tags, including the words YEOS and ANOYS which have appeared around Norwich station.

Anyone with information is asked to contact British transport Police on 0800 40 50 40 quoting reference number B04/026911 of 2010.
