A former University of New Haven student who pleaded guilty to federal and state charges of bringing loaded guns to campus in 2013 has been arrested again after police said he trespassed by riding a segway near two schools in Fairfield, police said.
The assistant principal at Fairfield Woods Middle School saw William Dong, 24, riding a segway on a driveway that runs between the middle school and Jennings School, police said.
Police previously warned Dong that he was forbidden from going on any public school property because of the gun-carrying incident at UNH during his time as a student there.
While Dong claimed to police that he didn't know the access road was actually property of the school, police arrested him, charging him Monday with first-degree criminal trespass.
In 2013, Dong prompted a campus lockdown and a building-by-building search after someone called 911 and reported seeing a man walking toward campus with a long gun, authorities said. Police found two loaded handguns on him and a Bushmaster assault rifle in his car that he bought out-of-state that is illegal in Connecticut, police said.
Forest Elementary School and Carrigan Intermediate School sheltered in place and Notre Dame High School was locked down during the incident due to their proximity to UNH.
Dong told police he had the guns to protect himself from mass shootings that had been happening and that he had the assault rifle in his car because he was going to the shooting range the next day.
Police said they found newspaper clippings of the Aurora, Colorado, movie theater mass shooting and 2,700 rounds of ammunition in the padlocked bedroom of his Fairfield home.
He was a commuter student and was been suspended following the incident, according to school officials, who said the code of conduct prohibits students from having guns on campus.
After that incident, Dong was sentenced to five years of probation after pleading guilty to federal charges and to eight years of incarceration, execution suspended after two years, and five years of probation after pleading guilty to state of Connecticut gun charges.
Fairfield police said Dong has legal gun permits for two handguns, but they haven't specified whether those are the same guns recovered.
No shots were fired during that incident and no one was hurt, police said.
