A Facebook post about Caitlyn Jenner prompted two grown men to duke it out in a west suburban office last week.

Buffalo Grove police say it happened in the 2200 block of Millbrook Drive on June 5 after Michael A. Moore, Jr. used a co-worker’s computer to hijack his Facebook account.

“Moore Jr. posted on his co-worker’s account status that he was attracted to Bruce Jenner’s female persona,” Buffalo Grove Police Lt. Tony Gallagher said.

The two men began “pushing each other,” and police were soon called, he said.

Once officers arrived, they learned Moore, 24, of the 2000 block of Century Point Lane in Glendale Heights was wanted on a warrant out of DuPage County.

Jenner, the former Olympian and reality show star announced last month that he was transgender and transitioning. Caitlyn Jenner debuted on the cover of Vanity Fair last week.
