Seattle Mariners outfielder Greg Halman was stabbed to death early Monday and his brother was arrested as a suspect, Dutch police said.

According to Rotterdam Police spokeswoman Patricia Wessels said police were called to a home in Rotterdam, Netherlands in the early hours of the morning and found the 24-year-old Dutch player bleeding from a stab wound. The officers and ambulance paramedics were unable to resuscitate Halman.

Officers took Halman's 22-year-old brother into custody, although no charges have been filed yet. Wessels declined to release his name, due to Dutch privacy rules.

"He is under arrest and right now he is being questioned," Wessels told The Associated Press in a telephone interview. "It will take some time to figure out what exactly happened."

Halman made his major league debut in 2010, appearing in a total of 44 games with the Seattle Mariners. Halman played in 35 games in 2011, hitting .230 and starting at each of the outfield positions before being optioned back to Triple-A Tacoma. He was Seattle's Minor League Player of the Year in 2008 after signing with the club as an international free agent in 2004.
