An arraignment hearing was held yesterday for the man arrested on drunk driving charges last week after pulling into the parking lot of the Ashland County-West Holmes Career Center while authorities were conducting a mock DUI crash event for students.  64-year old Mark Fulk appeared in Ashland County Municipal Court on Tuesday, where he pleaded not guilty to counts of OVI, having an open container in his vehicle and inducing panic.  Bond was set at $10,000 for Fulk, who is due back in court soon for his next hearing.
