Brian DeAngelis has resigned as Texas A&M-Kingsville's athletic director after just 80 days on the job.

The university announced the resignation in a terse one-sentence statement on Thursday. The statement said the move was effective Wednesday.

University Chief of Staff Randy Hughes told the Corpus Christi Caller-Times that DeAngelis didn't give a reason for his resignation. A message left at DeAngelis' home by The Associated Press on Thursday evening wasn't returned.

According to The South Texan, a news service out of TAMUK, DeAngelis was arrested for improper photography in a San Antonio Wal-Mart by the Bexar County Sheriff's Department on Sept. 17, and was released on a $5,000 bond. He was placed on administrative leave the next day.

Vice President for Institutional Advancement D. Scott Gines will assume operational control of the athletic department as a search for a new director begins.
