EXETER, N.H. - Frustration over lingering power outages is turning to outrage in some New Hampshire communities, and police say they are concerned for the safety of line crews.

Unitil officials say that in some cases, residents have parked cars in front of utility trucks to keep them from leaving neighborhoods.

Unitil spokesman Bob Schoenberger says in one case, a driver ran a line crew off the road to stop them. Another resident jumped on the back of a bucket truck and refused to get off.

As of Saturday afternoon, fewer than 24,000 homes and businesses in the state remained without power.

Unitil hopes to have all of its customers back online by the end of the weekend.
