This is a goof almost too good to be true.

Mob expert Jerry Capeci of Gang Land News reports that the feds — more specifically, federal agents with the Department of Homeland Security — were a little embarrassed a few weeks ago when they tried arresting Gambino crime family  capo Alphonse Trucchio.

The feds phoned Trucchio and told him to step outside his South Ozone Park, Queens home so they could arrest him on racketeering charges, according to Gang Land News.

Problem was, when Trucchio stepped outside, no one was there, Gang Land reported. Inside, shortly after, the phone rang again.

“If you don’t come outside now, we’re going to break the door down,” warned an agitated agent, Gang Land reported.

“Where are you? I just went outside and there was no one there,” said Trucchio, according to Gang Land.

The agents said they were outside his Howard Beach home.

“I don’t live there anymore,” replied the gangster, according to Gang Land. “I’ve been living here for 10 years…I’m on house arrest on an electronic monitor – and you don’t know where I am?!”

Gang Land reported that he then gave the agents the right address.
