An Ashland father and his son are behind bars after police found evidence of a commercial drug operation within close proximity to Ashland High School

Paul Kwiatkowski, 66, was being held on more than $1 million bail after Ashland police arrested him on felony drug charges stemming from a search warrant that yielded methamphetamine and prescription pills inside his home, according to Ashland Deputy Chief Warren Hensman.

Kwiatkowski's son, Charles Paul Kwiatkowski, 36, who was at the house at 94 Morton St. when police served the warrant at 7:30 a.m. Friday, was arrested for violating his probation on a third-degree robbery conviction.

Paul Kwiatkowski was being held on felony counts of manufacturing, delivering and possessing methamphetamine within 1,000 feet of a school, and on misdemeanor charges of delivering and possessing Xanax, classified as a Schedule IV controlled substance. His bail totals $1,025,000.

The search warrant stemmed from numerous neighbor complaints over a 90-day period, which Hensman described as "several, not just one or two" that came from multiple individuals. Hensman said he couldn't comment on the nature of the complaints while the case was under investigation

Hensman encouraged locals to contact police when they suspect drug activity in their neighborhood.

"Policing's a team effort," Hensman said.

Court records show Paul Kwiatkowski has no prior felony convictions, though he was charged with first-degree burglary in 1991 and first-degree sexual abuse in 1999. The burglary charge was fully dismissed, and Kwiatkowski pleaded down to a misdemeanor harassment charge in the sexual abuse case.

Charles Kwiatkowski has multiple felony convictions dating back to 2008, when he was convicted of possessing cocaine. His most recent conviction was a 2016 third-degree robbery conviction, in which he held a chunk of wood and a sharpened metal spike and demanded money from his father.
