A divided Ogunquit Board of Selectmen voted Tuesday to uphold the termination of the town fire chief following a tense meeting that culminated in more than 200 residents being asked to leave. The termination appeal hearing focused on the firing of Mark O’Brien, who had served with the Ogunquit Fire Department for 37 years before he was placed on paid administrative leave in June while town officials investigated complaints about his management style and interaction with his staff. That investigation led to his firing last month, a decision he then appealed. The hearing – held in public at O’Brien’s request – grew tense at times and the chairman ultimately had the audience removed when people began shouting comments at board members after a motion by Selectmen John Daly to overturn the termination failed.
