Three bullets pierced through a local ABC news station in California’s capital … and people were inside working when the shooter opened fire.

Cops in Sacramento say someone shot up the ABC10 news station downtown Friday afternoon … with police responding to reports of shots being fired just after 1:30 PM … and footage shows three bullet holes in one of the building’s windows.

Journalists were working inside the building when the bullets came bursting through … but incredibly, no one was injured.

ABC10 is an ABC affiliate … and the station broadcasts in Sacramento, Stockton and Modesto.

The station is owned by Tegna … and Nexstar Media Group recently announced a pending $6.2 billion deal to acquire all of Tegna, including ABC10.

Nexstar got the ball rolling on the Jimmy Kimmel suspension … it was first to announce it was pulling his show from its 32 ABC affiliate stations. Disney, which owns ABC, then yanked Kimmel from all of ABC.
