CCTV footage was today released of a masked man approaching an electric bike stolen from outside a Wirral convenience store.
Police want to trace the man believing he could hold "vital information" to help their probe into the theft of the bright green pedal cycle from Allport Road, near to Bromborough Wines, Bromborough.
The crystal clear video footage shows the bike propped against a wall.
The man, wearing a face mask and cap, appears to be heading into a doorway, but then stops in his tracks after spotting the bike.
He then walks up to the bike and the footage ends.
