PITTSBURGH — A man convicted of breaking business windows during the Group of 20 economic summit protests in Pittsburgh last year has been ordered to spend six to 18 months in jail.

Twenty-one-year-old David Japenga, of Pittsburgh, is getting credit for 4Z\x months he’s already spent in jail, but an Allegheny County judge refused his attorney’s request for an immediate release Tuesday. Prosecutors asked for a sentence of one to two years in jail.

Instead, Japenga may be paroled after he finishes serving his minimum sentence in a month-and-a-half.

He must also pay $14,000 in restitution and spend four years on probation after his release.
