A man was arrested at Trump Tower Monday night after the Secret Service found a knife, handcuffs, a firecracker, and a water pistol on him.

The man was identified by a New York Police Department spokesperson as Alexander Wang, 19, a Baruch College student from upstate New York.

The NYPD said Wang also had a garrote on his person when he was arrested. A garrote is a piece of wire, fishing line, or small rope used to strangle a person.

Wang did not get past security at the heavily guarded Trump Tower, which is President-elect Donald Trump's home and where he often works.

Wang has no prior arrests in New York City. He faces two counts of criminal possession of a weapon and several other charges.

Since Trump won the election, the gleaming Trump Tower on Manhattan's Fifth Avenue has morphed from a tourist attraction to a national security concern. The NYPD and the Secret Service are working together to protect the president-elect's home away from the White House, an NYPD spokesman told NBC News on the day after the election.

It wasn't clear whether Trump was in the building at the time of the arrest. On Tuesday, he was seen in the lobby of Trump Tower with rapper Kanye West, one of his many visitors.
