The Culver City bomb squad investigates potential explosives Wednesday, May 15, 2013.
Los Angeles County prosecutors say a 29-year-old man has pleaded not guilty to having bomb-making materials and other crimes after police found suspicious materials in his car and apartment.
Spokeswoman Jane Robison says Robert Colt Wilson of Culver City was arraigned Thursday on seven felony counts, including possession of methamphetamine.
Wilson was arrested Tuesday after police discovered a loaded weapon and an explosive in his car during a routine traffic stop.
Early Wednesday, a bomb squad inspected his apartment and found bomb-making materials and an explosive device there. Four blocks were evacuated as a result.
Los Angeles police said Wednesday that Wilson has no terrorist connections, and he appears to be a man who is just very curious about explosives.
If convicted, he faces more than nine years in prison.
