CEDAR RAPIDS, Iowa -- Cedar Rapids police say vandals shattered five windows at a mosque.

The damage at the Islamic Center of Cedar Rapids was discovered early Tuesday. Police say it was done between 10:30 p.m. Monday and 4:30 a.m. Tuesday, when members arrived for a prayer service.

Nothing was missing.

Police spokeswoman Sgt. Cristy Hamblin says it appears the vandals didn't go into the mosque.

She says the culprits used large rocks and other blunt objects to break an office window, two windows by the entryway and two glass doors. Damage was estimated at $3,000.
