FRESNO, Calif. (KSEE/KGPE) - A man continues to remain inside a northwest Fresno home almost a day after officers say he fired a gun off inside and then refused to leave the house, Fresno Police said. Officers say the ordeal began when they received reports of shots heard on Friday night around 10 p.m. They say they arrived to find a situation in which a person had fired a gun inside the home in the 3200 block of east Indianapolis Avenue, near Valentine Avenue.
