A Queens man who menaced a peaceful group of Black Lives Matter protesters with a bladed glove and then drove his car at them faces a long prison term after being convicted on nine attempted murder counts and other charges, officials said on Monday.

The man, Frank Cavalluzzi, was found guilty after a two-week jury trial, Melinda Katz, the Queens district attorney, said in a statement.

Mr. Cavalluzzi, 57, of Flushing, is to be sentenced in October. He faces up to 25 years in prison on each of the attempted murder counts, officials said.

“A dangerous man is going to jail,” Ms. Katz said. “It’s a good day for New York and the First Amendment.”
