PORTLAND — Police and local business owners will announce a new partnership Thursday to curb excessive and underage drinking.

Police Chief James Craig will release details at a press conference at 3 p.m in Monument Square.

In addition to police, the initiative will involve local bar owners, the Portland Nightlife Oversight Committee and 21 Reasons, a coalition to prevent underage drinking.

Announcement of the effort follows the death of Eric Benson, a Farmington man who was assaulted in Monument Square early Sunday morning, shortly after the city’s bars closed.
