Vice-president Barrie Spencer said members had worked hard to improve the site on Tudor Road, which was extremely run down, but returned almost every weekend to find some sort of vandalism.

“They thought it was single lined but it’s double lined,” Mr Spencer said.

The Men’s Shed members have used corrugated iron on the outside of the buildings to prevent vandals from smashing through the walls.
But sometimes the culprits chose to just “hang out” at the grounds and use the barbecue or throw things around.
Some time ago, a member came across a group of young people at the grounds and spoke to them.
“We don’t mind them coming here as long as they don’t damage anything,” Mr Spencer said.
“It’s costing us money to fix everything up and we just want to enjoy the facility.”
Mr Spencer said a lot of people walked past the Armadale Community Men’s Shed, which is behind Armadale Train Station, and he would like members of the public to report anything suspicious.
