The ‘ZERX’ tag has appeared on buildings and railway sidings

Police are appealing for information leading to the identity of a graffiti vandal who has caused �1million worth of damage across three boroughs.

The ‘ZERX’ tag has appeared on properties and railway sidings in Brent, Harrow and Westminster, resulting in the three councils and Transport for London with hefty cleaning bills.

The tag also appeared on the side of the Admiralty building in Whitehall following the student demonstrations in Central London in December last year.

Officers investigating the vandalism are appealing for anyone who knows who the author is to come forward.

DI Paul Armstrong said: “This tag has been scrawled across residential homes as well as schools, sheltered accommodation and historical structures and I would appeal to anyone who has information about the person who is responsible for this to contact police.”

Anyone with information is asked to call 020 8246 0050 or Crimestoppers anonymously on 0800 555 111.

A 21-year-old man arrested in connection with the graffiti has been bailed to return to a police station next month.
