Authorities say a New Hampshire man was arrested after he tried to move a parked ambulance that was blocking his car. Matthew Duval was charged Tuesday with disorderly conduct and unauthorized use of a vehicle, the AP reports. According to WMUR, firefighters and paramedics were inside a home helping a patient; they had unlocked the ambulance so firefighters could grab supplies. Authorities say the 40-year-old Duval couldn't get his vehicle around the ambulance, so he got in it and tried to move the ambulance himself. Workers heard the back-up "beeping" sound and called police. (More ambulance stories.)
