The move effectively represents a stopgap measure, extending Lang's contract 45-days from its expiration date on Jan. 11.
The pay rate, at about $40.87 per hour, is identical to what Lang obtained in his original two-year contract inked in January 2011.
The renewal agreement ends in late February, coinciding when city officials expect to hire a new full-time police chief.
