Healdsburg police said a prankster stuck a huge nail into the lawn outside the city's community center where a giant hammer sculpture was stolen from earlier this month.
The three-and-a-half-foot metal nail with the word "bait" etched on its head was found by employees around 8 a.m. Monday, Healdsburg police Officer Darryl Erkel said.
The 800-pound metal and wood hammer that measured 21 feet in length and six feet in height was stolen late on Oct. 5 or early on Oct. 6.
The artist, Doug Unkrey has offered a $1,000 reward for information leading to the arrest of the suspect or suspects.
Police believe the hammer was loaded onto a truck with a crane or by several people.
