Three men smashed their way into a Gedling house while the occupants fled in fear.
One of the men was carrying an axe and another was wearing a Scream-style mask during the aggravated burglary.
The occupants ran out of the front door while the men smashed through a window at the back and climbed inside.
Nothing was taken in the break-in, off Arnold Lane, Gedling, at around 12.40pm on Thursday 8 June 2017.
