A concerned passerby decided to call police when they saw a man angrily smashing a concrete driveway with a sledgehammer last month.
Horace Hughes got into an argument on January 13, the Whanganui District Court heard yesterday.
He grabbed a tomahawk, went outside, and began smashing the concrete, police prosecutor Sergeant Drew Morrison said.
The tomahawk then broke, so Hughes found a sledgehammer and continued smashing the driveway.
Mr Morrison said a passerby called police.
