PORTLAND — The chief of police in Maine’s largest city is going to ask staff in the city’s bars for help in taming rowdiness in a section of the city.

Portland Police Chief James Craig is expected to announce a plan to have doormen and bartenders use cell phone text alerts to notify police or other bars when they encounter customers who are unruly or drunk.

Craig tells the Portland Press Herald the problem is wider than the city’s Old Port neighborhood. He says when Portland residents can’t go into the Old Port after 10 p.m. it’s a problem for everyone.

Craig is planning to announce the plan Thursday in Monument Square, the location a Westbrook man was killed on Sunday during a confrontation.
