ST. PAUL (CNN) - A 23-year-old man was plotting to set off bombs to coincide with the Republican National Convention, according to details federal prosecutors released Wednesday.
The suspect, Matthew DePalma of Flint, Michigan, is charged with possessing Molotov cocktails, a type of gasoline bomb.
DePalma was locked up on August 30.
The criminal complaint also alleges that in July 2008 DePalma told an FBI confidential source that he wanted to travel to the RNC to “make some bombs” and “blow s–t up.”

Later in August, FBI audio recorded DePalma telling the source he wanted to build a chemical bomb to cause a power outage at the RNC, according to the affidavit.
He also expressed his interest in Molotov cocktails.
The source apparently went with the defendant to buy gasoline and diesel fuel, and witnessed the suspect creating a "flammable gelatin" for the bomb.
The document indicated that the defendant implied his main purpose was to cause a power outage at the convention hall.
The complaint said there was cause to believe he had five Molotov cocktails in his possession when it was filed.
