Clyde Vaughan, an assistant men's basketball coach at the University of Connecticut, was among more than a dozen people arrested yesterday in a prostitution sting run by police in Hartford, Conn.

Vaughan was charged with patronizing a prostitute and interfering with police after authorities said he tried to solicit an undercover officer for $10. Police said he struggled with officers when he learned he was part of a sting.

Vaughan, who will be entering his third year as an assistant for the defending national champions, was released on $2,500 bail.

A graduate and former player at Pittsburgh, Vaughan was an assistant at South Florida for three years and at Long Beach State for seven years before coming to U-Conn.

Vaughan could not be reached for comment last night.

A U-Conn. spokesman had no immediate comment. . . .

Psychological testing shows that Carlton Dotson, the former Baylor player accused of gunning down teammate Patrick Dennehy last summer, is not competent to stand trial, his attorneys said. They plan to file a motion today in Waco, Tex., asking the judge to delay the October murder trial.

* GOLF: NCAA champion Ryan Moore and Spencer Levin, the low amateur at the U.S. Open, were among 32 golfers who advanced with match-play victories in Mamaroneck, N.Y., at the U.S. Amateur.
