(Reuters) - A suspected tornado touchdown in Michigan on Thursday may have caused "lots of damage," including destroyed homes, near the town of Dexter, a county official said.

A dispatcher with the Washtenaw County Sheriff's Department said it was not immediately clear if anyone had been killed or injured.

"There are homes leveled at this point," he said.

The National Weather Service had earlier issued a tornado warning for parts of the county and urged residents to take cover.
