Sudbury police have charged a man with threatening death and public mischief after repeated calls to 911.  The man would call 911 even though there was no emergency to swear and yell at the operators.  He called them 20 times before Sudbury police dropped in on the accused and took him into custody.  But they had to detour to the hospital because while in the police cruiser the man wouldn’t stop banging his head resulting in cuts.  Once he was treated, he was put in a jail cell.
