Powder delivered to Judge Gerges’ office

Cops are looking for the menace who sent an envelope filled with a suspicious white powder to the offices of Judge Abraham Gerges, the jurist who cleared the last roadblock against the controversial Atlantic Yards Project earlier this week.

Police said that the powder, packed in an envelope addressed to Brooklyn Supreme Court, was discovered at 12:15 p.m. on March 4.

A secretary exposed to the powder was quarantined and decontaminated, although the substance was deemed to be “non-hazardous” later in the day.

The letter never made it to Gerges’ hands, police said.

Dozens of cops converged on the Supreme Court building on Jay Street, said witnesses, which was closed off for several hours as the investigation progressed.

By late Monday, cops were still trying to track down who sent the letter. It’s expected that investigators will be reviewing Gerges’ past and current cases, as well as his history in city government — he was a City Council member from 1974 to 1990 before he was elected to the bench.

Earlier this week, he threw out a final eminent domain challenge against the Atlantic Yards project, paving the way for its construction.

He has since moved on to overseeing a trial about a doctor accused of selling steroids, according to published reports.
