Dutch-born Seattle Mariners outfielder Greg Halman was stabbed to death in his homeland early Monday and his brother has been arrested in connection with the killing.
Details were not immediately clear, but the stabbing occurred in Rotterdam.
"A 24-year-old died this morning in a stabbing and we have arrested the 22-year-old brother of the victim," a Rotterdam police spokesman told Reuters.
The brother's name was not released.
"He is under arrest and right now he is being questioned," Rotterdam Police spokeswoman Patricia Wessels The Associated Press. "It will take some time to figure out what exactly happened."
The outfielder was born in Haarlem, Netherlands. He was a graduate of Mendel College, in Holland, and spoke four languages. Halman's father and brother played on the Dutch national baseball team, and his sister, Naomi Halman, is a professional basketball player in Europe.
The 6-foot-4, 200-pond Halman was seen as a power-hitting prospect, especially after hitting 33 home runs in 2010 at the team's Triple A team in Tacoma. However, astronomical strikeout totals tempered expectations. Last season, Halman was called up as a backup outfielder late in the year and batted .230 with two home runs and six RBI.
