The Mandurah BMX Club's new canteen, which members spent three years fundraising for, has been targeted by vandals for the second time in two months.
Club president Michelle Newport said members had raised $18,500 for the new canteen, which was installed on September 11.
“The windows were smashed eight days later and about one month after it was graffitied,” she said.
“The club had to pay more than $700 for new windows to be installed.”
She thanked the City of Mandurah for cleaning the graffiti free of cost.
Ms Newport said it was “terrible” to be targeted after such an extensive fundraising effort.
“It was really devastating after the amount of money that went into the canteen and the hard work by the club,” she said.
Mandurah Police acting officer in charge Anthony Nemeth advised the community to report suspicious or anti-social behaviour.
To report crime or suspicious behaviour phone 131 444 or Crime Stoppers on 1800 333 000.
