Sergeant Jason Dance, of the Warrnambool police family violence unit, said officers executed a warrant at an Iona Avenue address in Warrnambool at 7.20am this morning.

There they found 5.9 grams of crystal methylamphetamine.

"A 28-year-old man was arrested, interviewed and charged with offences including stalking, multiple assaults, breaching court orders, making threats and possession and trafficking ice," Sergeant Dance said.

"It will be alleged the assaults resulted in injuries. The man is known to police and has an extensive criminal history."

The man appeared in Warrnambool Magistrates Court about 2pm and did not apply for bail.

He was remanded in custody and will appear in court again on November 21.

Magistrate Peter Mellas said custody management issues included the man withdrawing from a drug of dependence.

Anyone with information about drugs is requested to contact Crime Stoppers on 1800 333 000 or the Warrnambool police station.
