RENSSELAER — Police on Monday arrested a Hudson man they say displayed a concealed handgun to Doane Stuart School officials inside the school Monday.

Pierre R. Jeune, 44, the parent of a child in the private school on Washington Avenue, has a permit to carry the concealed weapon, but he should not have had the gun at school, said Police Chief Rick Fusco.

Jeune entered the building just before noon looking for another person with whom he was involved in a fender-bender at the school a week ago, Fusco said.

The police chief said Jeune went to the school to speak to that person, whom he felt owed him money, and during his conversation with school officials allegedly lifted up his sweater, revealing the handgun.

School personnel called police, and Jeune got into his pickup truck and left. Police used his cellphone number to contact him and asked him to return to the school, and when he did he was arrested.

No one at the school was harmed, said Lisa Brown, the interim head of the school.

Students were never in danger, Fusco said. The school was in lockdown for a time, but that order was lifted after Jeune's arrest.

Jeune was charged with fourth-degree criminal possession of a weapon. He was arraigned in city court, released and ordered back to court March 13.
