The cop gunned down on the Champs-Elysees had responded to the 2015 Bataclan massacre and attended a Sting concert that reopened the theater a year later, according to reports.

“I’m happy to be here,” Xavier Jugelé, 37, told People magazine at the concert in November, a year after the Paris attacks that left 130 people dead.

“Glad the Bataclan is reopening. It’s symbolic. We’re here tonight as witnesses. Here to defend our civic values. This concert’s to celebrate life. To say no to terrorists,” he said.

Jugelé, who was gay, was an active member of the Flag! Association, which represents Lesbian, Gay, Bisexual and Transgender cops, the Telegraph of the UK reported.

His partner, who has not been named, also is a member of the association, although he is not a police officer.

Fellow cop Mickaël Bucheron, who heads Flag!, said he was shocked to find out about the death of Jugelé, who was a member of the 32nd company of the Paris police force’s public order and traffic division.

“Every time a police officer dies in the line of duty, all of us are very moved and affected by the tragedy,” he said, the paper reported. “But the emotion is even stronger when you knew him and he was a member of the association.

“It takes you a long time to grasp it. We haven’t got words to describe it,” said Bucheron, who described Jugelé as “a good guy, a nice guy and a committed, professional officer.”

The six-year police veteran also had made two trips to help refugees in Greece, the Independent of the UK reported.

Condolences poured in from the European Gay Police Association and several police unions, he said.

Flag! canceled its annual Tea Dance.

“It didn’t seem humanly possible to go and dance on Sunday when one of our colleagues fell last night,” Bucheron said.
