POLICE are investigating the whereabouts of a giant sign stolen from the side of the M62. The half-tonne sign, carrying the word Omega, disappeared between February 27 and March 1. It is worth several thousand pounds and was sited between Burtonwood Services and Marks and Spencer. Police would like to speak to anyone who travels on that stretch of motorway who saw what probably looked like workmen dismantling the sign. Call DC Steve Smith at Warrington CID on 652222 or Crimestoppers on 0800 555 111.
