New York City police say they've arrested a teenager who showed up at the Trump Tower security checkpoint with a knife, handcuffs, fireworks and a water pistol.

Authorities say 19-year-old Alexander Wang of upstate Poughquag, N.Y., was arrested at around 6:30 p.m. Monday.

The Manhattan district attorney's office said Tuesday afternoon that he was awaiting arraignment. There was no immediate information on an attorney who could comment on his behalf.

The Secret Service runs the checkpoint. The NYPD has a security detail at the tower.

“I always walk with them,” Wang said when asked about the weapons, according to the New York Post.

The busy and heavily secured Trump Tower lobby is a revolving door for Trump's high-profile guests, which included Kanye West on Tuesday morning. 

Though the building is privately owned, the lobby is a public space open 8 a.m. to 10 p.m. daily. The Secret Service randomly screens those who enter throughout the day.

The security measures are costing New York City an estimated $1 million per day.
