Police are searching for a man who's assaulted a worker during an attempted hold up at Norlane.

The man wearing ski goggles and gloves went into the Vermont Avenue milk bar around 9-30 yesterday morning demanding cash.

Police say he pushed and then tried to punch the male worker as he tried to get the till.

But the bungling bandit forgot to unplug the register, with the electricity cord making it impossible to remove.

He left empty handed on a mountain bike.
