Boulder police issued a dozen tickets for illegal fireworks over the Fourth of July holiday weekend, according to statistics released by city officials.

The city also reported officers received 92 reports of illegal fireworks over the holiday weekend.

Igniting fireworks within city limits or on open space property carries fines and penalties up to $1,000 and 90 days in jail.

For the second year in a row, Boulder police employed a “zero-tolerance policy for fireworks violations.”

People found in possession of fireworks this summer — or those who are caught lighting them — could be arrested. Those who start a fire with fireworks may face arson charges.

The hot and dry weather pattern led authorities to take the strict stance, and officials said they were motivated by extremely high fire danger in Colorado.
