CORVALLIS -- Investigators say a suspected arson at a Corvallis Islamic center appears to have been started by someone who broke a window and tossed a container of flammable liquid inside.
The Sunday fire destroyed part of the center where Mohamed Osman Mohamud -- the 19-year-old man accused of plotting a mass killing in Portland -- occasionally worshipped.
Corvallis police Capt. Jonathan Sassaman told The Associated Press the window to the center's office was not broken enough for someone to enter.
Sassaman says evidence -- including the entire window -- has been shipped to the FBI crime lab in Quantico, Va.
Meantime, Mohamud has pleaded not guilty to a charge of attempted use of a weapon of mass destruction in an alleged plot to set off a car bomb last Friday in downtown Portland.
The FBI has offered a $10,000 reward for information leading to an arrest in the case.
We have made it quite clear that the FBI will not tolerate any kind of retribution or attack on the Muslim community, said Arthur Balizan, Special Agent for Oregon. We are working very closely with the leadership at the mosque. We will find the person responsible for this attack and bring the full force fo the federal justice system to bear.
