The idea was simple: free bikes are left around the city. Anyone can just pick one up, and cycle off - as long as they put it back when they've finished with it. But the first lot of bikes vanished soon after the scheme's launch Now a new batch - all painted green - has been delivered. Police have warned that anyone caught stealing one will face prosecution.  Next News World Summaries Top Spout
