Naperville Man Barricades Himself After Machete Threats, Downs Police Drone

A 35-year-old Naperville man is facing multiple charges, including a felony, after he allegedly chased two apartment building employees with a machete and then barricaded himself inside his unit for several hours while police worked to bring the standoff to a peaceful end. Daniel O'Neill was taken into custody after the hours-long confrontation on the 300 block of North Charles Avenue, according to Naperville Police.

The incident began on August 12 when O'Neill allegedly threatened two apartment building employees with a machete, per Naperville Police. As reported by Fox 32 Chicago, the two employees took shelter in a maintenance room as O'Neill advanced toward them while armed with the weapon. O'Neill allegedly struck the maintenance-room door with the machete as the workers hid inside, though the incident resulted in no reported injuries.

Emergency dispatchers received the initial 911 call at approximately 2:03 p.m. after a resident brandished a weapon outside the apartment complex, according to a City of Naperville Public Information Office report cited by Positively Naperville. O'Neill then retreated into his apartment and refused to respond to repeated police attempts to contact him, per Naperville Police, setting off a barricade situation that would stretch on for hours.

Crisis Negotiators and a Drone Sent Inside

Naperville Police deployed trained crisis negotiators alongside members of the department's Special Response Team after O'Neill refused to communicate during the initial standoff, the outlet's report states. To assess the situation inside without putting officers in the line of fire, police sent a drone into O'Neill's apartment. The department's Unmanned Aerial Systems program, established in 2021, trains officers to fly drones for tactical SWAT operations and interior building searches, according to the Law Enforcement Drone Association.

According to Naperville Police, O'Neill damaged the drone and threw it out a window, disabling it. Officers also deployed a distraction device inside the apartment during the operation. State reporting compiled in the 2024 Illinois Freedom from Drone Surveillance Act Report and published by the Atlas of Surveillance shows Naperville police maintained two active drones and conducted 42 official flights between July 2023 and March 2024, underscoring how routine the tactic has become for the department even as this deployment ended in the equipment's destruction.

O'Neill eventually exited his apartment and was taken into custody, then transported to the Naperville Police Department. No injuries were reported among the building employees, O'Neill, or responding officers.

Felony and Misdemeanor Charges Filed

O'Neill was charged with criminal damage to government-supported property, two counts of aggravated assault with a deadly weapon, criminal damage to property, reckless conduct, and disorderly conduct. The criminal damage to government-supported property count is the most serious of the group. Under Illinois Criminal Code 720 ILCS 5/21-1.01, damaging such property valued between $500 and $10,000 is a Class 3 felony punishable by two to five years in state prison and fines up to $25,000, according to FindLaw.

The two aggravated assault counts, along with the criminal damage to property and reckless conduct charges, are each classified as Class A misdemeanors. Under 720 ILCS 5/12-2, assault while brandishing a deadly weapon other than a firearm carries penalties up to 364 days in county jail and fines up to $2,500 per count, according to Albert L. Wysocki Attorney At Law. The disorderly conduct charge is a lesser Class C misdemeanor, carrying a maximum penalty of 30 days in jail and fines up to $1,500 under 720 ILCS 5/26-1, per the Lawler Brown Law Firm.

What Happens Next Under Illinois' Bail Reform Law

Because Illinois abolished cash bail statewide under the Pretrial Fairness Act provisions of the SAFE-T Act, DuPage County prosecutors must petition a judge to hold O'Neill in custody pretrial by proving a clear and present public safety danger or flight risk, according to the DuPage County State's Attorney's Office. It remains unclear whether that petition has been filed or ruled on in this case.

The standoff is a stark exception in a city that has repeatedly ranked among the nation's safest. Naperville placed No. 19 among the top 25 safest places to live in the United States in a July 2025 report by U.S. News & World Report, based on FBI violent and property crime metrics, according to NCTV17. Separate crime analysis from IllinoisCrime.com based on FBI reporting found overall crime in Naperville dropped 11.2% year-over-year in 2026, with property offenses accounting for the vast majority of local police complaints rather than violent crimes.

Naperville Police are asking anyone with information about the incident to call 630-548-2955 or email [email protected]. The department has responded to a string of high-profile public safety incidents in the city this year, including an April bank robbery investigation that drew in the FBI and a home invasion search involving an Aurora suspect.
