[email protected] A veteran Williamsport Bureau of Police lieutentant claims in a federal lawsuit that he was passed over for promotions because he filed complaints on behalf of the Fraternal Order of Police Lodge 29 against anti-union activity. Lt. Steven Helm, supervisor of daywatch, this week asserted in the complaint in U.S. Middle District Court his rights to free speech were violated. The lawsuit identified Mayor Derek Slaughter, former Mayor Gabriel J. Campana and the City of Williamsport as defendants. Slaughter, who returned a telephone call for comment, said any statements regarding the lawsuit would need to come from J. David Smith or Austin White, the city solicitors and firm of McCormick Law.
