Trevor Lunn MLA said: “This is the latest in a series of alerts in recent weeks in Londonderry, where lives have been put at risk and disruption caused to residents. There can be no justification for the actions of those behind these incidents.
“This must have been a terrifying experience for this driver. He was providing a service for the whole community to make our roads safer on an icy morning, yet these thugs prevented him from carrying out his job.
“Those responsible pose a real danger to the public and must be urgently apprehended by the Police. If anybody has any information about this incident then I would urge them to contact the PSNI or Crimestoppers.”
