ATTLEBORO (CBS) – An Attleboro police investigation recently found a former veteran police official routinely issued gun licenses to people who were potentially dangerous.

WBZ NewsRadio 1030′s Kim Tunnicliffe reports.

The investigation finds that former Attleboro Police Sgt. Michael MacDonald issued at least 12 firearms licenses to convicted felons and people with mental health and substance abuse issues.

MacDonald issued a machine gun license to a person who had undergone alcohol treatment and another license to a man who had a number of run-ins with police.

It was recommended that MacDonald be disciplined.

No action was taken since he retired before the investigation ended.

His lawyer claims this is a case of dirty politics because MacDonald had filed unfair labor practice charges against the police chief and mayor.
