Knicks star Stephon Marbury was sued for $34,000 by a security firm led by a former New York City police commissioner.

The firm, SafirRosetti LLC, contends it provided security for Marbury between Jan. 6 and Jan. 19, 2004, for $42,312. Court papers say the player paid $8,000, leaving a balance, including interest, of $34,312.

An invoice from the firm dated Jan. 29, 2004, shows it provided 454 hours of "personal protection services" for the 6-foot-2 point guard.
