Former University of Washington basketball player Doug Wrenn, who was found guilty of threatening a motorist with a handgun three years ago, is in trouble again, this time for allegedly harassing a former girlfriend.

Wrenn, 32, was arrested April 16 and later charged in connection with the alleged harassment, said Seattle police. His ex-girlfriend told investigators that between April 13 and 15, he called her 46 times, sent her 12 text messages and nine emails. Many of the messages were deemed sexually explicit by police.

Wrenn had a hearing in Seattle Municipal Court yesterday, but court spokeswoman Patti McBride said that the judge granted a request by the defense to have the hearing postponed until May 14. Wrenn is being held in King County Jail in lieu of $350,000 bail.

In February 2009, Wrenn was convicted of two counts of second-degree assault with a handgun after he threatened two people at a Bellevue intersection in March 2008. He was sentenced to a year and a day in prison.

In that incident, Wrenn had been stopped at a red light behind another vehicle and honked his horn when the light turned green and the car didn't move. The driver pulled forward and moved into the lane to the right, Wrenn then pulled alongside the car, rolled down a window and began yelling at the people in the other car. He pointed a handgun at the driver and passenger.

Wrenn drove off, but was caught after the victim noted his license-plate number and called police.

Wrenn was arrested at his apartment in Bellevue. Police found a black Beretta pistol wrapped in a towel and jammed between a wall and a washing machine.

Wrenn, who attended O'Dea High School, played two seasons at UW. As a sophomore he averaged 19.5 points and was voted first-team All-Pac-10 by conference coaches after the 2001-02 season. His scoring average dipped to 12.7 points the next season under first-year coach Lorenzo Romar, and Wrenn chose to forego his senior season to declare for the NBA draft.

Undrafted, he played several years in minor basketball leagues and overseas. Wrenn last played in South Korea in December 2007.
