Man accused of dislocating cop's shoulder

A man allegedly tried to steal a police officer's gun before dislocating a female officer's shoulder and her male colleague's finger during his arrest.

The 39-year-old Morayfield man has been charged with a string of assault police charges following the incident north of Brisbane on Sunday.

Police say he approached them when they arrived to investigate a disturbance and tried to remove one officer's firearm.

He violently resisted arrest and spat on both officers, before dislocating the joints of two back-up officers called to help restrain him.

He will appear in the Caboolture Magistrates Court on Monday.
