MTA guard shoots screwball

An MTA guard restarting MetroCard vending machines at a Brooklyn subway station yesterday shot a man who lunged at him with a sharpened screwdriver, officials said.

The collection agent was confronted outside the Winthrop Street 2/5 station in East Flatbush by a wild-eyed man trying to enter around 2 a.m.

“He saw a man moving across the barricade tape so he calls to him, ‘There’s no service,’ ” said Transport Workers Union official Maurice Jenkins.

“The man took a swing at him and spit at him. He retreated and . . . the man produced a sharpened screwdriver. He took a swing at him and [the agent] fired one round to his chest.”

He was busted when he returned to the scene. He was in stable condition at Kings County Hospital. The agent was not charged.
