The owner of a Leeds lettings agent fought back when masked men armed with a hammer, baton and metal bar raided his business.
Three men wearing balaclavas and high-visibility jackets attacked the man at Catlows on Dewsbury Road, Beeston, and demanded he open the safe.
The Yorkshire Evening Post now reports that West Yorkshire Police said the victim fought back and the men fled empty-handed.
The agent was treated in hospital for cuts and bruises but was allowed home.
Anyone who witnessed the incident, around 4.40pm on Wednesday August 12, or who has any information should call Leeds CID at Elland Road via 101 or Crimestoppers, anonymously, on 0800 555 111.
