SA man charged over meat cleaver attack

A man has suffered a deep laceration to the face after being attacked with a meat cleaver during a home break-in in Adelaide.

His accused attacker has been charged with two counts of aggravated assault and aggravated serious criminal trespass over the incident early on Wednesday.

It's alleged the 27-year-old broke into a granny flat before attacking the 39-year-old.

Police say the accused lived in the main house on the property at Parafield Gardens.

When patrols arrived he initially threatened police while armed with a knife but after some negotiation gave himself up.

He has been refused bail to appear in Elizabeth Magistrates Court later on Wednesday.

The injured man has been treated in the Royal Adelaide Hospital.
