First, it was a window on the east side of the mosque. Then someone hit the south side. Later the west, then the north.
All four corners of the Central Minnesota Islamic Center in St. Cloud have been damaged in November and December, said Mohamoud Mohamed, a spokesman and member of the center's board.
Vehicles also were vandalized outside the center, located just north of St. Cloud State University on Fourth Avenue S., as well as outside the nearby Islamic Center of St. Cloud.
Police are investigating the broken windows and windshields, which have worried worshipers in the central Minnesota city.
"It is scaring us because there are children, elders, women coming here to practice their faith every day, five times a day," Mohamed said by phone.
Police Chief William Blair Anderson called the vandalism "disheartening and unsettling." While he can't say "with any certainty that these are all related," Anderson said, he doesn't think the incidents are a coincidence.
"I don't believe that much in coincidence," he said.
The latest problem came Monday evening: Several people inside the Central Minnesota Islamic Center heard a very loud bang, Mohamed said, and rushed over to find a big window destroyed.
