Greg Halman, a Dutch baseball player with the MLB's Seattle Mariners in 2010 and 2011, was stabbed to death in his native country of The Netherlands today.
His brother has been arrested in connection with the crime, according to reports.
"A 24-year-old was killed this morning in a stabbing and authorities have arrested the 22-year-old brother of the victim," a Rotterdam police spokesman said.
News organizations later identified the deceased as Greg Halman.
Of the brother, a police spokesman told the AP: "He is under arrest and right now he is being questioned. It will take some time to figure out what exactly happened."
Police found Greg Halman bleeding from a stab wound at a home in Rotterdam after responding to a call early today. They were unable to revive the baseball player.
Halman hit .230 for the Mariners in 2011, with two home runs and six RBI. The outfielder appeared in 44 career games with the club in a reserve role.
