The Seattle Mariners' Dutch-born outfielder Gregory Halman has been stabbed to death in Rotterdam, police said Monday, and his brother has been arrested in connection with the incident.

"We received a report at 5:40 am this morning that there had been a stabbing incident, Rotterdam police spokeswoman Patricia Wessels said.

"A 24-year-old man was found dead and the brother of the victim has been arrested and is being questioned," Wessels added, confirming the identity of the dead man as Halman.

"From what we have learned so far there was an argument between the two brothers over loud music being played," she added.

"An investigation is underway to determine exactly what happened.

"It was the victim's girlfriend who alerted the police."

Born in Haarlem near Amsterdam, Halman signed up with the Mariners in 2004 and played his first Major League baseball game for the west coast-based team last year.

Leading baseball magazine "Baseball America" regards him as the 57th greatest baseball talent at the moment and the greatest talent for the Seattle Mariners.
