Trump Tower remains one of the most heavily guarded buildings in New York City

Wang - whose full name is Alexander Yan-Nan Wang - told police that he was only in the building because he likes to study there, and that as a survivalist he carries the threatening items with him all the time.

He also explained that he'd visited Trump Tower ten times before carrying the same items without any problems, including two visits shortly after the election. He told authorities that he liked to go into the building 'to study finance'.

Wang also claimed to enjoy setting fireworks off down by the East River, and told police that he had more explosives at home.

Cops then raided his dorm room and found more fireworks inside an ammo box.

Authorities later raided his apartment where they found explosives

Police arrested Wang on two counts of weapons possession - for the hunting knife and the wire, or 'garrote'.

It's not known exactly what the garrote was made from. The weapon typically has handles at either end to stop the user's fingers from being cut on the wire as they strangle their victim.

Wang is from the city of Poughquag in upstate New York, and was highlighted as 'Men's Cross Country Rookie of the Week' by CUNY Athletic Conference in 2015.

His Facebook posts include photos of a crucifix and a Biblical quote.

Police said they found no evidence that he was linked to any militias or terrorist groups.
