THE HAGUE, Netherlands (AP) — Prosecutors say an investigating judge has ordered the brother of slain Seattle Mariners outfielder Greg Halman to be detained for a further two weeks on suspicion of murder or manslaughter.

Halman was stabbed to death early Monday morning at an apartment in the port city of Rotterdam. Police said his stabbing may have followed an argument about loud music.

Prosecution spokeswoman Jeichien de Graaff declined Friday to give further details of the investigation. She said an investigating judge ordered the extension of detention for Halman's 22-year-old brother on Thursday.

Halman hit .230 in 35 games and made starts at all three outfield positions for the Mariners in 2011 before being optioned to Triple-A Tacoma.
