CLINTON, CONN. (CBSNewYork) — A Connecticut college student who made national headlines with his gun drone now faces several charges in a separate case, including assaulting a police officer.

As CBS2’s Andrea Grymes reported, 18-year-old Austin Haughwout took video of the police stop in a library parking lot in Clinton, Connecticut last Sunday night.

Authorities said he was parked in a dark corner of the lot.

“The officer was merely attempting to ascertain why Mr. Howit was parked at the library at that hour,” said Clinton Police Sgt. Jeremiah Dunn.

Haughwout said he was using the library’s free Wi-Fi for a homework assignment.

The Central Connecticut State student made national headlines earlier this month for creating an armed drone labeled a “Flying Gun” on his YouTube account.

Haughwout said it was part of his mechanical engineering studies, which the school denied, Grymes reported.

Although alarming, law enforcement said there was nothing illegal about the armed drone.

Haughwout believes that was part of the reason he was stopped at the library.

“If you don’t suspect me of a crime, I’m going to be on my way. Have a good day,” the sophomore can be heard saying in the video.

“The officer pursued him, got him stopped about a quarter-mile up the road, at which point Mr. Haughwout refused to comply with putting the vehicle in gear or in park,” said Sgt. Dunn.

After some back and forth, police let Haughwout go, saying he refused a dozen times to put his car in park.

“Did not want to put our officers in harms way because he was in a moving vehicle,” said Dunn.

Police issued a warrant for his arrest for interfering with an officer and failure to obey an officer’s signal.

When he arrived at the police station, authorities said Haughwout refused to obey the arresting officer’s instructions and tried to leave the station, leading to a physical fight with police.

Haughwout was then charged with two counts of assaulting a police officer. Haughwout claims he was leaving to put his camera back in his car and was thrown to the ground.

Haughwout was arraigned and held on $20,000 bond.
