“I took 10 loose firecrackers,” the officer wrote. “I took one small bag of crack/cocaine.”

And one more thing: “A garrote.”

Mr. Tabois was charged with possession of weapons, burglar tools, a controlled substance, stun guns and fireworks. His arrest was reported in police blotters in The Villager and The New York Post. He has since been released on bail.

He listed his address as a home in Queens where no one answered the door on Thursday. He described himself on the LinkedIn website as a self-employed personal trainer.

Mr. Tabois has a history of arrests, and was twice charged with carrying a gravity knife, the police said. In Nassau County, he has an open case stemming from his behavior in court in April on a traffic matter. Mr. Tabois insulted the judge and raised his middle finger, even approaching the bench before officers stopped him, according to a criminal complaint. Mr. Tabois resisted, knocking himself and three officers into the courtroom seats before he was subdued.

In the Greenwich Village precinct near Bleecker Street, Mr. Tabois told the police he got the weapons from a dealer in Pennsylvania and had them shipped to his home, the police said. He said he intended to sell them on the street. Websites offering the weapons abound.

The contents of his backpack were full of surprises for most civilians, so H. Clay Aalders, managing editor of TheTruthAboutKnives.com, was asked by this reporter to characterize the collection.

“Wow, that’s a menagerie,” he said. “Let’s see how many banned things we can bring into the city.”

The weapons did not necessarily mean Mr. Tabois was a dangerous person, Mr. Aalders said. In fact, they suggested he was something else altogether.
