A Boulder High School teacher was arrested Saturday on suspicion of indecent exposure after police say he twice exposed himself to women at a community garage sale in Longmont.

James Kozlowski, 45, was booked and released on a summons from the Boulder County Jail on Saturday after police say he exposed his genitals to women at two separate garage sales taking place as part of neighborhood-wide event in north central Longmont.

“Apparently he came to the garage sales and he was wearing shorts and no underwear,” Longmont police Cmdr. Jeff Satur said. “During separate incidences at two different garage sales he exposed himself to females.”

Longmont police first received calls about Kozlowski’s alleged behavior at approximately 11:35 a.m. Saturday, according to a police report. Witnesses said that after exposing his genitals he left the scene in a new, silver SUV. Police used the SUV’s license plate number provided by a witness to contact Kozlowski, who matched descriptions of the suspect, according to the police report.

Kozlowski appears under the business, computers and technology heading of teachers and staff on Boulder High School’s website. He also serves as the boys golf coach.

Kozlowski, who graduated from Boulder High, coached the school’s girls basketball team to a state title in 1994. He was head coach of that team from 1992 until resigning his post in 2001, compiling a 138-57 record.

Kozlowski declined to comment on his arrest when reached by telephone at his Boulder home Saturday.

Boulder Valley School District spokesman Briggs Gamblin confirmed that Kozlowski is employed by the district but declined to comment on his arrest until district officials could gather more information.

“The district and administration will be reviewing the information from Longmont police first thing Monday morning and taking the appropriate personnel action,” Gamblin said.

Teachers are scheduled to report for the beginning of the 2012-2013 school year on Thursday, Gamblin said.

The first day for ninth-graders at Boulder High School is Aug. 15 with the rest of the student body starting on Aug. 16, according to the school’s academic calendar.

Indecent exposure is a class three misdemeanor under the Colorado Revised Statutes, punishable by up to six months in jail.
