A former Oshawa city councillor charged with abducting a civil servant in Whitby now faces 20 new charges in the case.

At a court appearance Thursday, Robert Lutczyk was charged with two counts of possession of a prohibited firearm, five counts of possession of a prohibited device and possession of a substance intending to endanger life.

Lutczyk, 45, now faces 26 total charges. He stands accused of abducting Oshawa city solicitor David Potts at gunpoint on Oct. 15. and then barricading himself inside an auto repair shop on Hopkins Street for 27 hours while police waited outside, trying to coax him out of hiding.

Potts, who was abducted as he returned home from a council meeting, managed to escape without harm.

Speaking with reporters last month, Durham Regional Police Supt. Brian Osborne said Lutczyk was upset with Potts over "business matters" involving the City of Oshawa, leading to the abduction.

Anyone with information about the case is asked to contact investigators at 888-579-1520 ext. 5400 or Crime Stoppers at 800-222-TIPS (8477).
