FAIRFIELD — The FBI is investigating whether a 47-year-old Fairfield man that held them at bay during a 10-hour standoff is linked to area eight bank heists.

Gregory

        Michael Ray Gregory of Ramey Lane is being held on an outstanding arrest warrant issued in July for a parole violation in Baton Rouge, La., where he was convicted of robbery.

        Additional charges of assaulting a federal officer and being a felon in possession of a firearm are pending against Mr. Gregory, according to the FBI.

        Agents were attempting to execute a federal search warrant at Mr. Gregory's apartment shortly after 5 p.m. Friday when someone inside the residence fired a shot.

        No one was injured, but police evacuated the three-story apartment building. A hostage negotiator was called in, and Mr. Gregory surrendered at 3 a.m. Saturday.

        Agents were looking for evidence relating to eight bank robberies in Tristate suburbs since September. The robberies:

        • Sept. 28: Firstar Bank, Batavia.

        • Oct 17: Provident Bank, Symmes Township.

        • Oct. 25: Provident Bank, Kenwood.

        • Dec. 12: Key Bank, Anderson Township.

        • Dec. 18: Fifth Third Bank, Fairfield.

        • Jan. 8: Firstar Bank, Batavia.

        • Jan. 23: Fifth Third Bank, Edgewood.

        • Feb. 6; Provident Bank; West Chester.

        In each robbery, the suspect was described as wearing a fake mustache and beard.

        According to the search warrant, agents were looking for a fake beard, fake mustache and other items relating to the robberies, including documentation of the purchase of a 1980 Buick.

        The apparent get-away vehicle used in the Jan. 23 Edgewood robbery — a 1980 Buick — exploded in flames on a dead-end residential street a few miles from the bank. At the time, police said the blaze was possibly a diversionary tactic used by the robber.
