The call came for all available units to respond to the area.

Blair County 911 then confirmed over the airways that shots were fired.

A call to be on the lookout “for officer safety” and a possible suspect description came at 8:43 p.m.

“APD officers are searching for a black male named Carlos with a 25-auto (caliber) driving a silver Buick Regal,” the dispatcher radioed. “Shots were fired.”

Details remain sketchy.

Altoona police said late Sunday that the incident was still under investigation.
