DALLAS, TX --The Dallas Zoo has reopened after police determined that a man who fled there to avoid arrest was no longer on zoo grounds. Police said the man remained at large Friday. He was wanted on a probation violation related to an aggravated robbery. Dallas police Sgt. Warren Mitchell says officers were serving a warrant at a nearby apartment when two men, including the one they wanted, ran and jumped a fence into the zoo. One of the men was quickly detained and later released. Police evacuated a portion of the zoo while they searched for the wanted man. No one was admitted to the zoo for several hours during the search.
